Flight left early and arrived early. the whole trip was excellent.

10.0 ExcellentNick, Jan 2025TPA - SEA

Flight left early and arrived early. the whole trip was excellent.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

Everything was great. Great service, excellent communication, and early arrival

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Good and consistent Printer in lounge did not work for me :(

Great - This was the last flight before hurricane closures and did a quick turnaround to get the plane heading north. Much appreciated.

I liked the screens in the seat headrest with movies to watch. I didn’t like being forced to check my carryon bag and being told there wasn’t room for my bag - when there were 5 bins sitting empty on takeoff. I didn’t like the “I don’t give a fig” attitude of the flight attendants and the delta gate attendants when I asked why they decided to put me out. They gave me a 1800 number to call but I can’t get a live person on the phone. Customer service is non existent. My business must not be that important to them.

It was not in Delta's control, but when we landed, we ended up parking at the wrong gate, and so everyone was already ready to deplane and had their carryon bags, ready to leave. But we had to sit down and move to the proper gate. This process took over 30 minutes. Again, not Delta's fault - more so on the staff at JFK

It’s was good. There’s so much room for improvement though. Since the plane was small, there was no entertainment but for years now, the most jarring aspect of travel is the lack of tasty snacks.

Love delta but the delays and long waits for updates was just too much this time.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

United left one of our bags back in SFO but that’s not my real complaint. The complaint is how it all went down. So we checked in the day before online and were told we could use the quick drop for luggage. So the next day I used baggage quick drop curbside at SFO. The agent mistakenly didn't tag my bag as he put my bag on the conveyor belt untagged. We immediately alerted him he had not tagged the bag. I walked with him to the baggage service office to find my bag and tag it. We waited outside the office for 10 mins. He came out and said everything was ok and the bag was going to be tagged and on my flight. We received a text that one of our bags was on the flight but the other was not. I alerted my first class flight attendant immediately upon boarding the flight. She was helpful and said she’d get it sorted out right away. She called over the gate agent. The gate agent used my bag number and looked over information on her device. She said my bag was on the flight. The flight attendant was standing with her, looking at the device, and also said “yep it’s on the flight”. During the flight the flight attendant made reference to how reassuring it must feel knowing the bag was on the flight. Upon arriving to IAD we received a text that my bag was not on my flight. The text said my bag would arrive to my final destination LIS 24 hrs late. I understand that mistakes happen. I was totally ok with my bag mistakenly not getting tagged at the quick drop. I was fine with walking down to baggage services to tag my bag. But, what I am not ok with is that the United staff said they fixed the mistake two different times, assuring me twice that my bag would be/was on the plane…and it wasn’t. I expected better attention by the employees, for them to do what they said they were going to do. We also spent extra money to upgrade our seats to first class, including the entire return leg from Lisbon to San Francisco because we wanted a smoother and more relaxing travel experience. Our money was not well spent. We will not be using United for travel going forward.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Horrifying! And I am almost 2 million miles with United. Late by 3 1/2 hours. Worst: after two hours on the plane waiting, they decided that one of the tires had been damaged and then decided to change it. Another hour and a half to change the tire!!!!! NO EXCUSE FOR THIS. The crew didn't even offer a glass of water until we had been on the plane for FIVE hours. This is the worst airline in the world. I'm simply stuck because they fly on the only routes I need.

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.

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.

ANA was great. United was horrible. They bumped us from economy plus to economy and were supposed to contact us for a refund but no luck. We booked the seats 9 months in advance.

I never have a good experience with American and this was no different. The airplane was INCREDIBLY hot. Like unbearably so. Everyone was fanning themselves with pamphlets and sweating. When someone asked the flight attendant to turn down the temperature they were told there was nothing the crew could do. Once we pushed back from the gate we then had to wait an hour to take off and the communication from the crew was not good. People were getting up this whole time and a man was even in the bathroom when we took off. Once we landed at our destination we waited another 30 minutes at the gate to deplane with, again, no communication from the crew as to what was going on.

I had a horrible experience from the time I dropped off my bags until the time I landed. The staff taking the bags at the check-in counter prior to security, forced me to check my baby stroller, even though it weighed less than 20 pounds. their excuse was that the wheels were too big. I have never had an issue gate checking this exact same stroller in the past either on American or on any other airline. when I asked for the agent to show me the rule about the size of the wheels on strollers, they told me to look it up on the AA website. I did so, and did not find any indication that wheel size was a problem for gate checking strollers. The only limitation would be the weight of the stroller which mine was below. I was left with a one-year-old child and all of my carry-on luggage, diaper bag, and the like to walk around the airport without the assistance of a stroller and had the same issue when I exited the plane and had to go all the way to baggage claim without a stroller. In addition, while on the airplane, I was told I can only get one bag of cookies as a snack, even though I was with a child. Apparently my child and I were supposed to share a cookie. While this latter issue is a minor one, it is just another example of the absolutely horrible customer service that American Airlines provides. In addition, the 737 aircraft that I was on was extremely hot and the air vents above the seat were so far away from the aisle and middle seats that it was comical. I could barely reach the air vent to adjust it. I had to ask the person in the window seat to do it for me. The whole experience was just a nightmare.

Ok. Got us there safely and a bit early. Need food available on this long flight. Almost 3 hours.

Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

Flight areas delayed 3 hours , train in the airport didn’t work

The flight was on time and everything went very smoothly.

We were offered Flight Change due to overbooking. We accepted and chose an earlier flight. We went to Rebooking center to make the change but agent told us no changes permitted on our Basic ticket. AA should not have made the offer to change our flight.

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

The flight attendants were talking the entire time on the back and I couldn’t even take a nap. Super annoying

Lower cost is the reason to fly Spirit. Should give free baggage with credit card.

From gate to flight crew... All Spirit employees were great! Everyone was kind and helpful. Ride was almost smooth... A few bumps... But no problems. Seats were tight and uncomfortable. Our biggest issue was no free drinks. I can understand paying for adult beverages and can understand no snacks on a 3 hour flight... But no drinks???? I had to pay $4 for an apple juice for my son. That's not right. You should probably reconsider that.

Great! First time flying with Spirit and I definitely loved it!

Better service, stop treating people like cattle, have REAL FOOD for the price of the ticket. YOU ARE IN BANKRUPTCY, WAKE UP!!! ... DO BETTER, PLAN BETTER, GIVE COMFORT AND CARE TO PASSENGERS ... EARN RESPECT AND ADMIRATION, YOU'LL BE REWARDED BY THE PUBLIC.

The check-in process at Spirit was horrible. There was no one directing the hundreds of people trying to check-in and drop bags at Spirit. We got in multiple lines and were later told it wasn’t a line. The check-in process needs to be improved. The flight and crew were great.

Absolutely Terrible. It was delay after delay after delay. I should have been arriving in Philadelphia at 12:05am from Fort Lauderdale instead I didn’t depart from Fort Lauderdale until 12:33am with no rhyme or reason as to why the flight was delayed. The only compensation we received were 12 dollar meal vouchers which by that time we were already boarding the plane and most of the place in the airport were closed so none of the vouchers got used because we were told that we could not use them on the plane .

It wasn't crowded, leg room was better for me (6'2"), less coughing on board, steady flight. Return flight is already delayed by 1.5hrs and that's not good.

Terrible, they lost my bad and it took three days to get it. First they couldn’t find it at all - Once they found it, the agents wouldn’t put it on the next flight, they kept forgetting. I went to the airport for a few Miami to Newark flights and finally found it. No one ever called to advise that it had arrived. Despite several calls, the bag made it without a tag, so I still had to go to lost and found at Newark. Our Christmas gifts were inside. Never flying with them again.

Horrible I was traveling with two assisted kids will never travel with spirit again

I’ve now flown Spirit a few times and while the general perception of Spirit I feel is poor, I’ve had a great experience each time. They do charge extra for everything but you should know that going in

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

The seats were extremely hard and uncomfortable. It was disappointing even for a budget airline.

Charging $74 for one checked bag is outrageous. I will never fly Frontier again.

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

At check in they don’t let you be with the person you are traveling with unless you pay $40 per seat . Really bad policy they have

The trip was unremarkable which is good. Crew was very professional and courteous.

Online check-in was not user-friendly. Too many fees, not cost effective.

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.

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.

I arrived 1 hour prior to boarding, and they said I was too late for a domestic flight. First time I heard that :-(
