The plane was delayed for over an hour because of a family who didn't speak English, and didn't understand what was asked of them. While I understand the delay, I thought it was unfair to keep us all waiting for over an hour to get to our destination and a better approach should've been exercised.

The plane was delayed for over an hour because of a family who didn't speak English, and didn't understand what was asked of them. While I understand the delay, I thought it was unfair to keep us all waiting for over an hour to get to our destination and a better approach should've been exercised.

Finally get a snack n drinks! Just like the good ole days!

The website said ear phones were provided in first class. They were not. But a lot of programs had captions

I didn’t make it because Alaska schedule my flight too tight, I had to run to the other side of the airport, and no one helped me get off the plane early or held the plane for me… so I missed it and it was Alaskas bad, not mine

The flight took off two hours late and involved a gate and plane change. It might have better if they had announced a problem from the beginning, not when we were boarding. Annoying, but better to be safe.

Overall flight was very very good. It was on time, plane was clean, staff was great, free WiFi was wonderful, especially for my young boys and did not have to wait tiling at baggage claim. The free snacks could have been better for children under 10, They did not like the biscuits/cookies and the pretzels were stale.

My experience was great! The crew is great always happy and friendly :) thank you Alaska!!

We were delayed over an hour because of fog at the destination--not Alaska's fault, but it still made the experience a little frustrating on the day before Thanksgiving.

We were amazed by the amazing food, comfort and service received in our coach seats. Pleasantly surprised we received breakfast and great beverages for no charge. Bag check fee was on $35. The crew was so kind and helpful. Highly recommend!

My seat was broken and there was tape over the light/call buttons...but overall things were smooth

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Coach seating is debilitating, neither my husband or I can walk the following day

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

A three (3) hour flight should have meal service in First Class, not just potato chips!

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward into a very uncomfortable position and it is not removable.

Just about made it for the next flight. They need to put in longer layovers if they know they close the gate 10 min before they take off. I will never do a layover for less than 90 minutes

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Best flight by a pilot I’ve ever been on as a 62 year old

Boarding, Seating, Flight Attendants, flight was okay. My seat was uncomfortable.

Late and next flight even later. Who leaves at 245 am and arrives at 330 am ? No wifi, 4 hr flight and one bag of pretzels? AA should be ashamed

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?

A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .

terrible cascading delays and unhelpful customer service. uncomfortable plane. crew was great, however!

I ended up paying $70+ dollars to for a carryon because the website is confusing and misleading. I now realize I did not need to pay that. I request a refund. I will pay extra to other airlines and not fly Frontier again.

With frontier you get what you pay for. The flight was two hours late. It’s a tight fit for the number of people they bring but you get to where you’re going cheap. Sometimes that’s more important than a nifty drink and cool TV..

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

Although we received an email from Kayak AND the airline, turns out we were not on Frontier’s manifest for the flight. We had to purchase tickets at the gate. Not sure where this transaction fell apart, but it did. We are now disputing the charges for the SLC to PDX flight originally booked through Kayak.

We had an awful experience getting our bags checked in. Frontier’s check in on the app manipulated us into buying the business package because that was the only option available for a checked bag which included two checked bags per person which we did not need. Upon arriving to the airport, we stood in line for what seemed like forever at the baggage check in and there was no one available at the counter. We were first in line and we were afraid we were going to miss our flight due to the baggage attendant being late. After realizing there were a lot of other people waiting at the baggage check in and no one available. I reached out to Frontier and could not get any customer service so I had to call the airport to page the baggage attendant to send someone to the counter to check in our bags before we were able to go through security , I finally spoke to the attendant at the counter and explained to her that we had to pay for two checked bags person a total of six bags when we only had a total of three bags between three people she said to reach out to Frontier and they would issue a refund for the three bags that we paid for and did not need. I reached out to Frontier which I was not able to reach anybody by phone so I had to go through their automated chat feature, which sent me around in circles until I finally reached a representative to assist me. I explained to them what happened and they explained that they were not able to assist me. I continued to push the issue with them as this was very frustrating and they finally put in a customer service ticket where we were issued a flight credit and we were so disappointed because after this experience, we NEVER want to fly Frontier again, and we do not want a credit that we will not use. Frontier charged us almost $500 for us to check three bags which is absolutely absurd! The customer service agents were not able to offer anything else other than a flight credit and I do not feel like my frustrations were truly heard , we will never use Frontier Airlines again ! Truly Theft by Manipulation! They should be ashamed!

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time

One crew member was rude about our bags. Be nice about it. We don’t fly a lot. And the fact that you have to pay for a carry on is ridiculous
