I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Aside from a completely packed plane, I really have no complaints.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

Excellent business class seats, service and food. No airline does it better.

The only negative thing was boarding a Copenhagen-bound flight in Toronto. The middle aged woman at the desk gave me some bad time, claiming they wouldn't allow me to board the flight, switching to russian in the process. After I asked her to speak English and explained her that I had to reroute with the airline due to flight cancelations that where beyond my contro and will be leaving the Shengen zone promptly, she told me I had to check in my small bag because the flight was full and they needed someone to give up their cabin luggage. After I refused, she told me she would have to check my bag if it fits the allowed dimensions, which it did. I understand she's not an SAS employee, I understand she needs to check the documents and also make sure there's enough room for overhead bags on a plane. What really made me mad was her hostike tone and the beyond poor communication skills. Basic politeness would go a long way.

The stewardess was incredibly rude. The gave you only one drink with dinner.

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

Crew members were excellent. The seat wasn’t the best as well as a food options.

5 of my 7 pieces of luggage are missing and they cant call to find out where it is. I have to fill out a form and wait for them to mail it to me in several days (if they find it). That does not work for my travel itinerary. I need my full ticket cost refunded please.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

The crew was friendly, the flight was pleasant. Thank you for your service!

Flight was completely full January 9th? I problem i had the stewardess was bumping into me constantly walking by? very annoying.. on Austrian air I dint have this issue at all...

Amazing! Everyone was so nice and the food was so good!!

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

Late- that’s what United does best. Missed my connection, rebooked to a flight 17 hours later and had to spend $500 on a hotel. What did I get? A $15 meal voucher. What can you get in an airport for $15. I hate United so much.

Late plane. Only one crew on the ground so we b had to wait for Denver flight to come in, board, and depart. At 78 yrs of age I was not pleased trying to get my connection. What really made me angry was the notification you sent me to hurry up or I would miss my connection. Why tell me to hurry up when you got me in late. It was not a good way of treating customers.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

We were a little disappointed to not be able to complete check in online without uploading pics of passports. Also we have KTN's and they weren't on our boarding passes when we got to security. Had to trek back to counter to have them fix.

Excellent service in Polaris class IAD to ZRH. Arrived rested and well fed after the overnight flight.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

It's a short hop. My carryon was checked at the gate, I didn't have to drag it all over the airport. Excellent wheelchair assist.

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The wifi experience is awful. I had to try again and again, taking over 30 minutes, to connect to the wifi. I had to watch the same two ads over and over until I was finally successful. Once connected, it was anything but "high speed" and disconnected at least three times during the flight.

Fine. Nothing to write home about. The plane left on time, and arrived on time.

I was downgraded from first class to coach due to an airplane change. They pulled me out of line and I was the very last person to board the plane stuck in the middle seat with no overhead place to put my carry-.on. Very poor customer service.

Seat comfort was poor (no lumbar or lower back support).

The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.

STOP MAKING THE SEATING SO CRAMPED. WE NEED A PASSENGER BILL OF RIGHTS!

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

We had several flights and they were all on-time and flawless

My Frequent Flyer nber wasn't put on as I was told it was..... This resulted in a last group boarding and no priority tags on My bags.
