Seats very comfortable and legroom appreciated. All in all, it was a great experience.

Original flight was canceled, and the automatically booked second flight was immediately delayed. I arrived about 4 hours later than planned with only a $12 meal voucher that didn't fully cover a sandwich at airport prices.

I was expecting better service from Alaska Airlines. I registered for assistance since I have a disability. The terminal in Seattle, WA was very unprofessional and at times rude. The BWI location was the exact opposite. I will NOT consider Alaska Airlines for future flights.

It was very good and comfortable, Crew was also great

The flight was delayed almost an hour. No wifi on flight.

Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though

Delay of more than 3 hours I didnt recieve neither a voucher for food Attention disaster

Flight was 1:20 later than booked & I never received notice. At airport way too early. Couldn’t hear announcements on PA system. Crew fine. Retrieving luggage fine. Overall experience not good.

I will never take a red-eye flight again. Crying babies. Complete full flight. Could not get comfortable. Not fun.

Flight was OK, landing not good, boarding was ridiculous. Flight was to load at gate n11 25 minutes before boarding time it was changed to s5 which is 3 tram connections on the other side of the airport, I'm handicapped and even getting a sky cap took 10 minutes needless to say just made it to boarding only because it was delayed. I did learn a valuable lesson don't show up for flight 2 hours early.

The way BCN airport handled boarding was a huge improvement over our trip to Spain from JFK. Instead of gate-mosquitos edging in before their zone was called, in BCN they had clearly marked lines for Zones 1-8 and people just lined up correctly. The flight itself was uneventful. The meal (curried chicken and rice) was one of the better meals we've had on Delta. Entertainment options were plentiful, power chargers were available in Main Cabin, and seats were decent. Flight staff were very friendly and positive throughout the 8 hour flight.

I like for how they process during check in. It was very smoothly.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Boarding was tough as we had to take a bus out to the plane and walk up a lot of stairs. Difficult with heavy carry-ons that said I got an entire empty row of seats, which was excellent for an international flight. Food was very mediocre but happy with the comfort so not complaining.

Subject: Complaint Regarding Disrespectful Behavior by Delta Air Lines Staff at Boarding Gate Dear Delta Air Lines Team, I am writing to formally file a complaint regarding the behavior of a staff member at the boarding gate today, May 14, 2025, at Las Américas International Airport. While we were preparing to board flight DL-1829 to New York, scheduled for 2:28 PM at gate T-11, we were informed that the aircraft was experiencing water system issues and that passengers were advised to use the restroom before boarding. I politely approached one of the Delta staff members to ask whether the lavatory would be partially or completely unavailable during the flight, as I am traveling with a baby in my arms. The employee’s response was extremely rude and arrogant. He replied, in an unnecessarily hostile tone, something along the lines of: “It’s either that or we cancel the flight — do you want us to cancel the flight?” This response lacked any empathy or professionalism. I understand that technical issues can arise, but that does not excuse such inappropriate treatment of passengers. I felt deeply disrespected and disappointed by the interaction. I sincerely hope appropriate measures are taken, and that all staff members receive the necessary training to treat passengers with courtesy, especially in delicate situations like this one.

This is speaking of the original flight leaving on April 30th(DL 1957) not the rebooked the following morning DL 9887. On April 30th, it was unusually crowded at Sangster International Airport (MBJ) the morning my mother and I arrived for our flight. She had to exceedingly long time for a wheelchair, once a wheelchair attendant arrived to take us to thru immigration and security then to go to gate the flight was boarding. We stayed on board for 3 1/2 hrs until the flight crew notified the passengers that flight indefinitely delayed so we had to stay by gate area. Before that my mom had to wait an additional 20-30 mins to deboard the plane. Was given food vouchers, by the time I came back the gate agents said the flight was gonna to reboard, so all the wheelchair passengers lined up. We waited an additional 45 mins, while I received a notification from kayak that the flight was cancelled. And on my delta app updated that flight was being detoured to Miami then from Miami back to JFK. We boarded the plane started to eat, then the flight crew notified us the flight was indeed being detoured & that how come the gate agents didn’t notified the passengers. We stayed on board for another 30-40 mins then was told by the captain that they tried all avenues to get the passengers back to JFK but the crew couldn’t continue the journey and the flight was cancelled. So we deboarded the plane again. Was told that we were going to be setup in hotels for the night. The hotel that we setup to go to wasn’t suitable for my mother’s needs and requested one nearby we were located in Jamaica. So any we had called a taxi to come to take us back where we stayed in Jamaica, that we had to pay out of own pockets.

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

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

Everything was ok!! Just bags came up a little be late.
