It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

My window shade didn’t work. So I missed coming into my city. ☹️

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

Everything was pretty good except for food. They need to improve on it compared to other airlines.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

Not worth the premium paid for the first class ticket

Not worth the price of premium class ticket paid, felt more like steerage.

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!

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

I had a great flight. Everything went smoothly and the flight arrived early.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Missed this flight due to the first AA flight delay

Equipment swap led to 2+ hour delay on international flight. And to top it off, boarding took forever.

Wretched scheduling - they got themselves into a critical crew situation and didn’t try to address it until 15 minutes before they had to cancel my flight

They cancelled two flight and got us onto another airline, which was also delayed.

Nothing, terrible travel experience due to weather and maintenance delays and was left stranded in Austin.

Missed connection from Philadelphia to London because flight from DC was seriously delayed. Was re-routed the next day (had to pay for hotel) to Zurich and was given a main cabin middle seat while I had paid for premium. Great job AA!!!

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!

28 hour delay at Fort Worth/Dallas airport, part due to weather which was unavoidable, but various other reasons - no pilot, no fa, mechanical problem, plane too small, too big, crew out of flying time, seat configuration problems.... endless and hourly updates with a different excuse. Finally told us about 3.00 am, that the flight was delayed to hours later.

Terrible legroom, seats do not recline, tray table the size of an iPhone, delayed flight, have to pay 5$ to get a cup of water onboard.

Could have TV/Movie and some water ou soda free

Flight was good and clean but delayed over an hour on the return flight.

The non stop flight and able to go into Atlantic City airport. They could lower the prices. It starts out low but then if you want to bring luggage and pick your seat the price goes up quite a bit.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

We can’t predict circumstances like this ahead of time, but I give your staff a hats off for immediately giving us updated informations.

It was nice! There was a very unhappy child in front of us and the flight attendant did a great job calming the child. I was impressed.

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

EVERYTHING WAS WONDERFUL HOSPITALITY THE HELP.THE SEATING FRIENDLY ALWAYS HAVE A GOOD RIDE NOT ONE BAD EXPERIENCE WITH THEM

This was the smoothest flight I have had in awhile. I was also offered an exit row seat for a great upgrade cost and was able to sleep almost thr whole flight due to comfort and a smooth flight. We left on time and arrived on time.

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

9 hours of delay!! Was not able to check my luggage that I paid for!!!

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

I am very disappointed with Frontier Airlines. They cancelled our flight because they couldn't find a crew member, and then didn't get us to our connecting flight. We had to cancel our whole vacation. We were promised flight and hotel vouchers, but they never sent them.

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

It was ridiculously hard to check in for the flight, and Frontier charged us a LOT of money to have a carry on suitcase, and then told everyone we could not carry on bags and had to check them through at the gate, and didn't refund the extra money we paid to have the suitcase as carry on.

I had a terrible experience with Frontier. I arrived before the 60 minute cut off and was told that Frontier has a two hour window for bags. I was then told the next available flight wasn’t until the end of the day (I had booked a 6am flight). I took a look around and saw other people being told that they could not board their flights or that they had to pay additional fees. I opted to rebook on American Airlines. There’s absolutely no straightforward way to contact Frontier, so this ticket was a complete waste of money. Oh - and the kicker is that the lady lied about the two hour cut off.
