Airline reviews

Flight Staff: Always great! Checking back vs carry-on: I typically check my bag since so much time is spent stowing the bag, it's heavy, maybe not enough room. Delta is charging $45 to check bags. Yet, the people who have multiple carry-on bags are then asked to check their bags and are offered this service for free. This does not seem fair to a person who is trying to be proactive in improving the process . Boarding: Boarding is always slow and exhausting. With the exception of First Class, Economy, why not board the zone in the back of the plane first??? Seats: Why cross the seat belts? I get that it looks nice, but people waste so much time moving them or sitting on them and then having to move. Seats: On both my flights the seat did not recline. Not a big deal. Smell: There was a horrific smell like the restrooms on my first flight. I thought I was going to be sick. Most flights do not smell great. Does Delta use air purifiers or anything?

DL482 did not wait for about 10 of us including a mother and 3 children when we were in the same terminal on DL486, where we were switching from waiting for a jet bridge fix, to moving to a neighboring gate. I understand taxiing delays are ok either but man. We only needed 5 more minutes. DL482 did not adjust from their times at all. This was my first time with Delta.

The actual flight was smooth and we arrived earlier than expected which was great. The flight attendants gave unclear instructions and were rude. They seemed overwhelmed or flustered for the flight. Inflight service was delayed and unsure why.

There needs to be better accommodations for waiting passengers. A a designated standing space that is separated and away from concourse traffic.

overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.

N Everything was perfect from boarding to assistance to baggage in Tampa

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

The flight attendant in first class was beyond rude and didn't care at all about her job. AND the gate agent was even worse than the flight attendant for rudeness. She was awful.

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Flight was delayed 5 hours. Updates kept changing. Sears were extremely cramped. Very little leg room. Flight attendant was rushing through with drinks and hit me in the knee either the cart and didn’t apologize. They gave a 15 dollar voucher in airport which doesn’t buy. Much and it was so late that choices were limited.

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

The flight was delayed because they closed several flight ways because of air shows, fire works, etc.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Gate 461 the worst in LAX Boarding lacks professionalism And as usual, your food sucks.

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

The flight was really crowded. Flight attendants were just ok.

It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.

While waiting to claim my checked luggage, I discovered the airline had lost it. After a long wait and inquiries, I discovered it was on another flight. Fortunately, the airline finally sent my luggage home.

It was the worst experience ever. Cabin temperature cold, for which they did not have any blankets upon my asking. We paid $125 extra for each passenger to get extra space sits; the sits were ridiculously small, tight, and uncomfortable! The flight attendant dropped ice on me and my sister! All in all, American Airlines deserves below zero!

The inability to be flexible when you need to change a Basic Economy flight, when your company demands you book through a third party, causes raw feelings about the whole experience. A major airline should realize business and personal plans change all the time. I must save my company money on travel. Even if you have to charge me for the change, I get it. But being so rigid with a policy is not the best customer service.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

We are gluten free, there were not any available complimentary gluten free options.

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.
