Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

Entertainment is ok! Boarding and seat with zone is terrible. I paid for the seats but you didn’t give me what I paid for which is exit isles.

the crew cancel the morning service due to the weather. Then the flight got deverted to Nashville . we were on the ground for over two hours the only gave us water once... no food or any snacks.... the crew should have handled better and offered something to passengers.

My recent experience was excellent on Delta! I flew with Delta Comfort and I was really comfortable in my seat. I enjoyed the in-flight service. The flight attendants were so friendly and hospitable. I love the snack on the flight as well. This was my first time flying on Delta and I will definitely consider flying with them again.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

Mechanical Delay of over an hour with multiple gate changes. Entertainment system down for rejuvenation.

I had a flight cancel and had it rerouted. When the rerouted they put me at a window seat instead of an isle. It was hard sitting by the window because the couple with masks on were making out. I get motion sickness which is why I need to have the isle seat.

NEVER MADE THE FLIGHT BECAUSE DELTA SAID THEY CAN NOT

THEY FAILED ME AND I NEVER GOT ON THE FLIGHT BECAUSE IT WAS SO DELAYED! I ENDED UP HAVING TO PAY OUT OF POCKET FOR A HOTEL AND STAY IN NASHVILLE TO CATCH A FLIGHT FOR THE FOLLOWING DAY. DELTA IS POOR CUSTOMER SERVICE>

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

The flight attendant was friendly and efficient. The temperature was kept nice and cool. The plane was nice, but filthy. There were visible spills on my tray table. The gate agent was somewhat rude with her announcements and in speaking with other customers.

I appreciate that I finally got the seat I paid extra for this time. Thank you

I would have liked vegetarian and gluten free options for evening dinner time flight. I would have like a pillow on the international overnight flight . The veg wrap and oaten desert on the international flight was good

The experience at checkin for my American Airlines flight from Sacramento to LAX was very good including the assistance I received in getting my bags checked in and boarding passes printed. Was pleasantly surprised the my bags were checked through all the way to my destination at Clark International Airport in Angeles, Philippines.

Very poor food. Took more than 90 minutes for baggage to arrive at DFW

British Airways is an excellent airline. Comfort, food and airline personnel.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Terrible planning. And even worse gate agents. Absolutely rude behavior.

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.
