This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Delta is a cut above the others in customer service.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

I love the free WiFi!! Crew was nice. Bathroom was decent. First time flying delta in a long time and I enjoyed it. Will definitely look into booking with Delta more but I think Delta is a little more expensive than the other airlines.

third trip overseas with delta recently where the TV did not work- not acceptable for a 8 hour flight! your food really has declined crew great and I am loyal to delta

Boarding in Amsterdam is always chaotic. KLM/ Delta has not streamlined or made it efficient as it was boarding in Detroit . The food was mediocre The crew was unfriendly and more focused on getting things done quickly rather than service with a smile .

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My suitcase was destroyed. The top part where the handle is is completed broken. And unusable now.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

Everything was good. Flight was on time, luggage pickup was quick. The staff were great. Could not ask for anything more.

The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.

Any sort of gluten free snack option would be nice

I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.

On time arrivals and departures. Gate boarding notices could be better if displayed on monitor.

Between Las Vegas and Dallas was okay But, once in the Dallas airport, notice, I have disability and ask for a wheelchair, they leave in a middle of nowhere, the personal in charge try to push me on a cart where I couldn't sit because was to high. Then they don't care about me, they bulling, till I start to yelling and crying, ask to everyone around, who can help me. The man in charge make a despective movements and said you are to loosing the fly. The last name in his batch started with an H, I did not have the full name. A nightmare. After all, a woman in charge was walking very slowly and asking me for a tip cause she was helping me to reach the fly. For years, AA has been the preferred airline. The personal in charge of the disabled people are discriminate me. Thank you Kayak.

American Airlines Suck. AA did not deliver us to the airport we paid for to Tulum. Instead, we were flown into Cancun and had to take a shuttle to Tulum. Instead of arriving at 4 PM, we arrived at 11:30 PM - not to mention that our initial booked flight was due into Tulum at noon. The latter flight was canceled and rebooked (to the 4 PM arrival). We lost a day of vacation. Oh, I forgot that AA provided a lunch voucher for $12. Noting, the least expensive item on the menu at the airport restaurant was green beans for $9.99. The return flight from Tulum was delayed two or three times for no reason other than that it was NOT related to the weather. We arrived late for our connecting flight from DFW to STL. Luckily, the connecting flight was delayed. We hurried through Customs and ran through the airport to make our flight to STL (or we would have missed that flight).

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

2/29/2025: Tulum to DFW. Delay as usual with no explanation from AA. Three friends and I had a connecting flight from DFW to STL. We would have missed the latter without the delayed connecting flight, dashing through customs, and running through the airport. Did I mention our trip to Tulum on American was rerouted to Cancun and shuttle from Cancun to Tulum, arriving at our resort destination at midnight vs the 4 PM scheduled arrival? AA provided a lunch voucher for $12.00. The least expensive menu item was $9.99 for green beans. I will avoid traveling with AA as much as possible.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

April was the flight attendant in first class and was the most pleasant, cordial and efficient person I have seen on a flight in years. Good example of the type of people AA should hire to increase customer satisfacdtion.

crew was great, wifi was very poor could not even load a youtube video

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

First flight out in the morning is often the best chance of running on time. Not in this case, which unfortunately is now what passengers can expect as what is common. - If you are late for a flight, too bad for you. - If West Jet is late, too bad for you. - Bags don't make it? Too bad for you. - Flight change by 1+ days, too bad for you Prices continue to increase, while customer service nosedives. This is backwards and in any other develop country would be considered unacceptable - except for Canada. Too bad for us.

Experience was good. Was surprised they didn’t offer a complimentary meal on a 5 hour flight.

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

The flight attendants were great, but not much room while sitting and it would be nice to get free movies.

Original flight canceled and communicated poorly. A series of gate changes , delays and plane changes followed. Even after the entire flight boarded there was another plane changes followed. Food vouchers provided to my travel companion but not to me despite being on the same reservation. No in flight entertainment. The entire experience was terrible although the flight crew were great.

It was great being a direct flight from Calgary to Tokyo. No transfer to worry about.

Very old planes. Seats were not comfortable. Air was not on during the flight leading to incredibly stuffy conditions.

Traveling on two legs the food was identical and not very good

Not much....we did not get the complimentary beverages promised in our ticket. My partner and I did not have the window seats promised. We didnt get to sit together.....

It was great. Although when I got my luggage it was broken.

I liked not paying for carry on and the compensation my husband and I received from the airline for overbooking our flight. The staff was very friendly and helpful.

It was a short flight and for that reason the flight was acceptable.

The seats really could do with some extra padding. The staff member who checked me in at Calgary was amazing. Friendly and lovely.

The trip from booking to execution was great! The plane from YVR to YYC had LCD panels for entertainment which was great, but the return flight from YYC to YVR did not have them. Oh well--it was a short flight. Food was a pretty minor "token" snack, but hey--it was a short flight. It could have been skipped entirely and I would have rated the flight well.

As previously mentioned in last review , seats are small and uncomfortable, and baggage fees are high!

We got home a day late because of mechanical problems and that they wouldn’t put us on available other flights.

They were so kind and helpful and they even brought an item of mine that I forgot on the plane!!

Terrible. Frequent last minute flight cancellations with terrible rebooking options!
