Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

Southwest continues to do less for more money. Flight attendants used to be fun and friendly. But now it’s like they don’t even see you. Such a shame.

I liked it better when you were truer to your roots Am paying more for less fun

We had a 5 hour delay on the tarmac in Baltimore

Long layover between flights to Long Island from BWI - need better coordination between flights

The last 3 flights between BWI and BDL canceled the beverage service mid- way. Just say up front that the fight is too short. Thanks!

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

David went above and beyond to make our flight the best that it could be

The crew and flight was amazing. I haven't flown United in years but plan to switch to you being my main airline

Wouldn’t let me check in said couldn’t find a ticket had to wait very long Time

Seat cushions were worn down and it hurts as I seated under 5 hours of the plane ride.

I wish I had another choice. Domestic flight in the USA is atrocious.

Flight was delayed, boarded, sat at the gate for more than 30 minutes, left the gate then waited on the pad for another 30 to 60 minutes then returned to the gate, deboarded and was cancelled... alternative flight was not booked automatically. Waited in line for 30 minutes but fortunately an alternate flight to a different destination was found ... no thanks to the travel agent used by kayak

The flight changed gates multiple times and flight had to be delayed multiple times

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

I like that the crew kept us informed but we moved back and forth from gate to gate before the aircraft arrived.

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Was as expected. Good leg room on planes - much appreciated.

Boarding went fine, the plane was clean, and the crew was very friendly. Seats were a bit cramped, but that seems to be typical on all airlines anymore. Cookies and pretzels were offered as were beverages - the usual. I’d fly American again.

Inbound plane was on time and flight departed on time with no issues while boarding.

After boarding and un-boarding twice over 6+hours, the flight was canceled.

We were delayed three times ,and that destroyed my plans, and reservations

The Boarding process in Denver was chaotic, and since the line was so long, we were lined up very far from the gate. If there were any announcements from the gate staff, we didn't hear them. The flight attendants were spectacular. The only negative part of the flight was sitting by a 2 1/2 year old who was unruly and unfortunately had parents that matched his behaviors. Also, the restaurants in Denver on the E concourse, they didn't have food (passengers could only order 1 item on the entire menu) or the restaurants had 12-14 people waiting for orders to be prepared and another 6 people waiting to order. If you have a layover in Denver and need to grab food, be prepared to visit the shops with pre-packaged sandwiches, or you can visit another concourse but it may take a while to transit throughout the airport.

The reps working at the airport counter were dumber than a second coat of paint.

Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?

Airline changed the gate from Terminal A to Terminal D which is quite far and only sent a text message few minutes before boarding. Around 50 people missed their flight and as plane didn’t wait for them.

Bad experience… crew are extremely strict with personal bags… they overcharge me coz my bag was one inch H

30 minute delay due to boarding and settling of a family.

Flight was fine, but the legroom between seats for taller passengers is very tight and bad on the knees. I t is very hard to find an angle, that works, especially on a long flight!!!
