Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Getting to the flight was arduous and lengthy. The flight itself was good but the food option wasn’t a good selection. I need to do a Kosher option on my return. Flight crew were nice

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

Overall it was good. I missed my connection but I was put on another flight.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Attendants were pleasant and the flight was smooth and relaxed.

It was fine. No drinks nor snacks offered though. I thought that was unusual.

Things were delayed a little. But that didn’t affect my plans. It was fine. I was surprised it was so full thanksgiving day. The crew were friendly and professional.

The flight was delayed multiple times, again no fault of American but again the extra cost, for everything makes it feel like a cheap airline! Especially when flights are outrageously expensive already

we landed at cmh ten minutes early but had to sit on tarmac for twenty minutes because a plane was at our gate despite the fact that 3 other gates were open.

I have a gluten allergy so did have any food

We were very rushed by a staff member at the gate when transferring from American Airlines to Fijian. Then the plane stayed put for ages anyhow! The plane was delayed and my bag sent to San Francisco instead of Fiji

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

The only thing to like was that we eventually got to our destination

I like the crew they're very friendly. I don't like. on five hour flight they not offered snacks. Any drink. Not even coffee

Not even water is offered on the flight. You cannot lean back on the seats and the seats are so narrow you can’t avoid rubbing elbows with the person next to you.

I couldnt recline the seat. Other than that crew was very attentive and helpful. Thsnk you

I had to go to the boarding counter for them to enter my return flight as it’s not with Avianca. There was a long queue as there were lots of people being called to the counter.

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.

Boarding, crew were excellent, food was ok and entertainment need to improve

The seats were uncomfortable and barely reclined at all. Very little leg room despite being business class. The crew was friendly and the food was good. Had to use my own phone for in-flight entertainment.

No food, terms when selling are not clear. To pricy for the service in general
