It was canceled. Supposedly weather. But there was no snow in Baltimore. At least we found out before driving to airport

I have not flown Southwest in awhile and had a very pleasant experience. From ticketing to boarding to the flight. The flight left on time and landed ahead of schedule. It won't be so long next time!!

The Southwest experience has definitely taken a dive from its early days. You can no longer deferentiate from other airlines. Air travel is too expensive. Southwest is no longer budget friendly. They have lost me as a loyal customer.

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

An entire day of delays. Cost lots of money. Meals and a hotel.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

Flight was warm for first few hours and quite rough

Seat was extremely hard which made even a short 1 hour 20 minute flight fairly uncomfortable.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

two hour delay and the Delta representative on the PA system was unable to understand

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

2+hrs delay without any reason provided and a cramped flight

We waited an hour on the runway to get a gate in Orlando

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

Flight got delayed; had to go through security three times.

A lot things happened in this trip.The fly should be less stress.

There should be a warning regarding the quality of the aircraft on the website as we reserve the tickets. There was no TV or any type of screen onboard. The wifi they offer is good for nothing. Traveling 9 hours straight with kids and no type of entetainment was horrible. I wish I had been informed prior so I could buy a ticket with another airline. The food was a joke too. A very tiny portion per passenger. They also charged $100 per checked bag. With United I used to pay $60. So, fair to say that I wont be flying Copa anymore. Their aircraft was super old, outdated, no entertainment, with nearly no onboard food.

The flight was good overall. Everything went smoothly, although the landing was a bit rough. Still, it was a pleasant experience

I always enjoy flying Copa. There are very few airlines where I can enjoy a comfortable sleep in-flight. The snacks weren't the best, but they sufficed. The in-flight entertainment was fantastic, and I crossed another movie off my watch list.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

It was a train wreck but on an airplane. First off, flight was delayed then we board only to hear two announcements, First weather delays in Orlando and second backup battery warning on emergency lights. After sitting on the plane for almost 2 hours they have us deplane due to the maintenance issue. We were told they were getting another plane. In the mean time, I notice another American- Orlando flight and ask the gate agent if I can switch. He says he cant help me and I'd have to walk to A13 from A37. Really!? I get down there and get a seat only to get an announcement my original flight was RE-boarding. The Then inflight there's no communication and I notice on flightaware were circling over the Gulf of America. I call the flight attendant and of course she has no clue and apparently 5m later the pilot finally tells us about another delay. Why does American always have these service and delay issues? They are my LAST choice in flights now!

Mediocre would be best description. Food bland. Seat biz class uncomfortable to sleep. Crew never dimmed lights completely in an overnight flight to Europe. Would avoid AA if possible.

For my arriving destination, we were delayed multiple times to the point that we arrived 6 hours after we were originally scheduled. On my flight home, they overbooked and involuntarily removed passengers (including me) from the plane. It was not a good experience.

It was good experience this time. The flight was on time.

I very rarely fly American and my experience today reenforces that is the correct decision. While the staff were all very courteous, our flight was first thing in the morning so there was no reason to be delayed, yet appropriate maintenance checks weren’t completed prior to our flight so we were delayed multiple times. Not a great showing, American Airlines.

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

Small plane, poor meal choices for first class, bad terminal and boarding experience at LAX

Lack of gluten free options in food service. I have Celiac disease and it appears you no longer offer special meals for people with dietary restrictions. I am a frequent flyer traveling into and out of Omaha airport. I have noticed over the course of several months that although our flight typically arrives ahead of schedule (awesome job AA!) - we typically sit on the runway for several minutes waiting for the ground crew to get in place. Not sure if it is a ground crew issue or a gate availability issue (due to construction at this airport). Seems to be more of a ground crew being on time issue.

Arrived early picked up my bag in a few minutes- great trip - thank you

bought basic spirit fares, add checked bags - like the up front info on website about this. bring your own snacks, buy a soda after TSA security to bring with you, or buy on the plane (limited selection) all in all, a good experience

I cannot effectively rate the food and drink as I had not. Otherwise, the trip was fine. The seats were nice, the crew was fine. They could smile once in a while. They all look like they were mad.

4 hour delay, 2 hours in the airport and then 2 hours on the tarmac. With a flight full of kids it would have been better to leave us in the airport for the delay, it was crying kids chaos on the flight. Miserable. And no apology or airline credit for the significant delay.

Flight was on time with no issues. Price is very competitive. Flight schedule works well for me

They charged late fees for selecting seats (no $0 options). They also changed my gate within the last half hour and are refusing to reimburse my costs to drive across the country with two small children in a rental car.

I was waiting in line for the restroom onboard, the flight attendant told me to step back two rows and stay on the carpet. She was rude and I expected a tik tok experience with me getting thrown off the plane. She was rude and frankly there was no where else to stand.

I needed a cheaper option than Southwest who are almost as bad as Spirit...did the check in the morning of the flight and assigned the last row, middle seat. Paid 20.00 at the airport for an exit row window in 19 and all 8 rows behind me which sold occupied on their seat map were empty....so they force to you to pay for a better seat....I was alone in row 19 and shortly after take off two huge fat people came and grabbed the other seats, I rang the call button for the attendant and said I paid 20.00 for this seat and they just moved in here...I either want to be reseated, or have them take their original seats or a refund of what I paid, the attendant made them move back to their original seats. Worst, worst worst airline in the air....never again, never again, never again.

It was cancelled a few hours before take off. Spirit has yet to confirm I will be refunded for the trip

gate agents with the different rules at the different airports. made me pay for my bag as a carry on instead of a personal item, yet it fit under the seat on the way from Indy to Ft Laud

charging $3 for really bad and cold coffee on airplane flight is ridiculous.
