Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

Not pleasant. We arrived several hours late and my friend and driver were waiting for me a long time at Tucson airport. At first we had to divert to phoenix due to shitty weather. Well, i guess I can’t fault anyone for that. But then when they refueled , they overfueled and we had to wait even longer for the plane to burn off excess fuel. So someone really screwed up there and should get fired. Human error is really inexcusable.

Left on time. Arrived on time. That’s all i ask.

Flight was changed from departing from Boston to departing from Detroit.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

Canceled last minute. Also canceled another flight that my brother was supposed to be on. Delta is horrible now. Never flying them again.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

cancel my non stop flight for no reason. And force me rebook 2stop flights automatically then get short time to catch my flight from Atlanta to Charlottesville. We missed the flight then ask me rebook again to another city Richmond which far away 90mile from Charlottesville. Spend all day for flight and spend Uber from Richmond to Charlottesville airport cause my luggage was sent to there earlier half day and my food was bad cause heat. Damn delta

Like all flights, the seats are small and not comfortable. My first leg was delayed but delta rebooked 2nd leg so my arrival at final destination was only 2 hours later than original flight.

Didn't make it dir to delays - no support from United staff

My flight was delayed for a whole day, so I lost a day of my vacation.

flight delayed, was put on another flight after standby queue, luggage was misplaced and arrived to me 3 days later

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

I’ve had a couple flights this week on United that were delayed by an hour or more

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

seats were way too small. Too short of a flight to offer amenities.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

American is a steady for me. I always get what I expect from them. Sincere effort to get me from one place to another.

BAD. As a family could not sit together. The gate agent told us there was only one seat in the middle left, when we got on the plane the situation was very different with whole rows of seats empty

Plane was delayed an hour causing me to miss my flight to London and now I am not arriving until Sunday instead of Friday. I am stranded at airport and they give me $12 of food vouchers. It's a joke and everyone I talked to was rude

The Airline was not prepared for weather delays. We were held up due to an incoming flight being delayed and so we did not have a flight crew. This caused an extra delay for departure by 2 hours.

The plane was freezing cold. Normally I’m fine on planes but I needed to toss a sweatshirt on this time.

I missed this flight due to delays on my previous flight.

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

Cancelled after 3 hour delay with no aside from a rebooking three days later.

Nothing. Will never ever travel on Spirit or Frontier. Both of them Garbage Airlines.

Good experience between checking in all the way to baggage claim... waited 45 minutes for our bags in Portland. Waited for an hour when we landed in BWI... they brought half out-quickly. The others took the hour.

There was no water offered to passengers during a four hour flight, five hours on the plane. There is no entertainment on board. The crew interrupt everyone often to sell credit cards and reward packages. Other than that, pretty typical flight. You get what you pay for.

Someone opened my checked bag and stold75 euros Not happy

Terrible experience, will definitely NEVER fly with Spirit again (this was my first AND last time). They canceled the flight JUST minutes before we were about to board, with no warning, no reason, and no recourse. We managed to get on a different, much more expensive one-way flight home (with United) later that night, and arrived early the next morning, although by that point, the garage with our car had already closed for the day. So we were left having to pay an exorbitant $200 Uber ride to get home. Trying to fly with Spirit is definitely “penny wise and pound foolish,” absolutely NOT worth whatever meager savings they promise (and then still nickel and dime you for everything from water to a carry-on bag).

Three out of four legs of my trip were delayed. The last leg of my trip was delayed due to passengers and crew not being ready to take off. The boarding process started way late with no explanation as to why. The flight attendants did not have the passengers in check for takeoff - folks were walking around, trying to change seats, and causing a general disturbance preventing us from departing and the crew did nothing about it. All of this caused us to miss my connection home due to the first flight landing at the same time the second one was due to take off. The entire Spirit crew (except for one flight attendant) was unapologetic and unpleasant about this. No one apologized, no one showed any inkling of empathy whatsoever. The response was basically, "we booked you on the next available flight". That next flight was a full 24 hours later, we would have been stranded in the airport and no one even cared or acknowledged us as customers. I'm disappointed in the lack of compassion shown by Spirit agents and customer service reps as a whole. It felt like we were a burden due to airline scheduling issues. The one flight attendant (did not catch her name, but from (ORD to FLL) was wonderful and empathetic.

Poor response to delay, getting on plane, off plane and back on again

Flight was canceled less than 6 hours before takeoff, rebooked on a flight that was twice as long and left earlier so we couldn’t make it, when using text support option took over 2 hours to speak with someone.

The plane was not on time for boarding or departure or arrivals.

25 dollars to get a boarding pass abusive nasty folks at the boarding pass check-in desk flight delayed abusive nasty personnel at gate no one knew what they were doing at boarding a real cluster fbk I took a different flight back frontier socks

Flight was canceled as soon as I got to the airport

I was unable to check-in on your app at home before the trip. I didn't realize that you charged to get a boarding pass from the couter. I stood in a long line to check-in to be told that I needed to get in another line to get a boarding pass and that it would cost me. When I spoke with the lady at the next counter, she couldn't get me into the check-in on my app so she tried several other ways over about 15 minutes while others were waiting in line. Finally she was able to get into the check-in and then it took a while to click through multiple upsale options to get my pass. I thought it should be easy since I has a personal pack and no seat selection. I was traveling alone to attend a family funeral.

I didn't like anything about the flight It was my first time and definitely my last time boarding a frontier flight. Their counter agents need training and they need to learn to communicate regularly and respectfully

Booked two aisle seats and were switched to an aisle and middle. Not happy.

Our flight was cancelled and I spent $800 on a replacement ticket. No refund was awarded other than the cost of my original Frontier ticket. unacceptable...

The last time I flew Frontier was in the 1960s when it was a “real” airline. We flew this time because of the price & schedule. As the saying goes, you get what you pay for.

Horrible my trip was delayed 3 hours, we already have set in the plane and they delayed the flight.

Frontier’s bag policy is ridiculous and they made me pay $100 just to bring on a tiny ukulele. They were rude and not willing to budge. I was quite frustrated

The worst experience ever!!! They canceled our flight when we arrived at the airport to check in. We asked why is it canceled they told us they don’t know. No apology, very cold and rude. We had to pay for another night at the hotel, we had to call out of work. We won’t be using them anymore in the future!!!
