Mario was great. Made a night flight on a small aircraft pleasant and memorable.

It was great I love flying Delta and have never had a bad experience with them

They were 2 hours late departing with no explanation. I missed my connection, was rebooked not in correct seating that I paid for. Over all of was horrible. I now know why I've not flown Delta since 2018

Excellent flight from boarding to landing. Plane crew was informative, warm & attentive.

I love the free wifi and headrest screens. I would consider Delta even more because of this but the seats aren't so great. The snacks aren't very good in my opinion. I bought a Bloody Mary and that was great! So just be comfortable with better snacks and the airline world will be yours.

Crew was not helpful. Other passengers in first class were over served blatantly over intoxicated.

We just spent $6000 on our first trip since pre COVID and we were stranded on the runway of our departing airport for 2 hours and 15 minutes while our layover was only an hour and a half. We were told by the pilot we were next for de-icing and then got bumped by 3 other planes. Pilot went on to say they only had one guy working the de-icing where they usually have at least 2. In Rochester. In the heart of winter. Someone missed a step and should be fired. I'm not done.

Food service was bare-bone. Better bot to have any at all rather than hand out premade coffees and cookies to random few passengers.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Terrible. Delta delays caused us to miss our flight and they did nothing to fix it.

Well, flight times cause some wait, but there were not times available and we understood. I didn't check any luggage, because it has become too expensive. I was able to add any extra items to my co-travellers check bags. [Luckily, this trip wasn't international.] Last, I hadn't flown AA domestically for a while, but partners and coworkers had warned me in advance that not all planes have monitors at every seat. Luckily, I was mostly prepared to use the in-flight entertainment and happy I was. The great: AA staff is always kind and comfort is way better than the budget airlines that I sometimes have to fly. I know my points and vouchers all expired over the last couple of years, but I still enjoy AA when I do fly with them. I also appreciate all of the locations we can go directly from pur home airport. Since we are traveling more now, I hope to take advantage.

Poor on time performance. Flight was delayed due to a lightbulb. No updates from the pilot. Plane was dirty and hot, AC didn't work well.

Perfect flight. On time departure and early arrival. Smooth flight.

It was right on time and crew were very courteous

Charlotte airport is miserable. For American I always have to connect from the end of terminal E to the end of terminal B and the stupid moving walkways are always broken. And the flights to all seem of least importance so they never leave on time in either direction.

Cut off carry ons, had to check, got on and there was plenty of bin space. Disappointing.

Nice clean modern plane no issues with the b flight

Being back games on the in-flight entertainment. Also your flight attendants need a break, raise, or overall attitude adjustment.

Flight attendants used to be nice to people. And any flight over 5 hours should have some kind of food other than tiny pretzels and one drink comped.

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats are better cushioned then some

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

Nice easy flight. Crew was very nice and of all the times I have bought a seat for my guitar - this was the easiest. They were prepared and no problems at all.

Air Lingus flights were delayed on each of the three flights we took. Not a very good , and organized airline.

Flight was ontime, clean, staff was friendly - there was turbulence but can’t avoid that (it’s a flight 😉)! The staff were attentive but would be nice if Aerlingus didn’t charge for coffee ☺️ but overall I enjoyed my flight experience and will travel with them again (Ireland’s Four star airline

It is a low cost airline. Staff are courteous. There is no entertainment. Food is purchased.

Upon boarding, the people at the gate were extremely rude, there were no outlets on a 6 hour international flight, there was no entertainment, all food and drink was purchase only (even snacks), and my seat reclining function was fully broken. The only redeeming quality was the flight attendants were extremely nice. This was by far the worst flight I have ever been on in my entire life

I don’t know how international flights can’t have media screens to keep people entertained for the long flight. Ugh.

Typical experience for budget airline. Boarding from KEF required bus transit from the gate to plane, so if you had "priority boarding" it was useless as it was simply a free-for-all when getting off the bus. But still no issues with getting our luggage into overhead bin so not really a problem.

Was very apprehensive about flying Play, but the flight was fine. Nothing special, nothing horrible. Fair price to get from New York to Iceland.

I wasn’t able to check in online the day before or the day of because their web configuration or business model idk. I arrived an hour early and check was closed and there was no one around to speak to and eventually was told there was no possible way to get a digital ticket despite I had no luggage to check and would have easily made it through security to boarding and had to pay for a new ticket for $330 ontop of the $169 I spend for the ticket and then I missed my rental car for $305 because I only arrived at midnight instead of noon that I was originally intended. All booked through kayak. I hope there is some kind of insurance from kayak because this was totally preventable had I not been blocked by play air from getting my check in and plane ticket.

The staff was very professional, the places very clean. The legroom was a little bit tight but so worth the price of the flight. Very pleased! Next time, I want to book a stayover to explore Iceland :)

The boarding process was easy, the crew was friendly and the flight was very smooth. There is a limited menu the food was tasty, but you have to purchase everything. The cost of the flight was very reasonable but everything such as baggage is extra.

Play is a great budget airline. There are no TVs or chargers in the seat but there was more legroom than expected. Boarding and all staff that I interacted with were great. You have to pay for any and all drinks or snacks you might want on flight.

Play is a great budget airline. There’s more legroom than expected, no TVs or chargers in the seat, all staff that I interacted with were great.

Pre flight food options were not working and made the flight not enjoyable. Post experiences of British airways have been positive, but this is enough to stop me using British airways again

I was rebooked on Delta. Did not take this flight

Flight cancelled and i was rebooked on delta. Delta business class is not the same as British

Boarding could be smoother. But the flight crew was excellence. Very professional, friendly and helpful.

Everything was fine except my screen wasn’t working and I was unable to watch any movies or TV. Staff tried 3 times to reboot it, without success.

Boarding ,checking in was easy and quick . Comfort was not good.

It was good… always SO many people… I realize that’s how they make money but wow!

Positive boarding experience, easy access to seat with plenty of luggage space

Undocumented cargo processung delayed flight 1 hour. After getting all the way out to take off, we had to go back to gate for 45 min + processing & refueling. :(

Truly felt "taken care of". Will definitely fly British Airways again.
