I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Two delays on two separate planes with parts they could not easily find and replace.

I like the lane and orderliness and timely everything was executed. Amazing

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

Boarding was a mess, they call all priority members without distinction so gold, platinum, silver were all mixed together in a long line which defeats the purpose

Avoid at all costs. My wife had to stay back on a connecting flight as her parents flight was delayed. 10 days later on the way back they cancelled all our flights. We had to rebook all four of us on the next days flight.

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

A lot things happened in this trip.The fly should be less stress.

Some of the Air hostesses are not that friendly. Need improvement

I liked the meatloaf the chicken was awful but the plane was on time and got there and the staff was nice.

Boarding was quick & efficient; they gave boarding groups due priority; staff & air crew were very cordial and helpful, pleasant flight.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

A flawless trip, great experience. Keep up the good work!

The airline did not allow enough time for the Columbia checkpoint

Seats are absolutely not comfortable and large enough. There’s a limit and you stepped over it. I understand that there’s a business class, however for the price it costs, it’s just plain stupid for a 50 minute flight.

The crew was great! They waited for me as Air Canada flight was delayed by 1:15 hours from Ottawa to Toronto. I am a bit disappointed that we could only use wifi for entertainment but I survived! The only thing I would of liked is a more comfortable seat. The seat cushions are not thick enough for flights longer than 3 hours. Aside from that, everything was great.

After boarding, there was a small issue with the aircraft which caused a delay of about 45 minutes. During boarding and while passengers were being seated, the plane was being refueled. There were also a lot of unusual noises during the flight, which was not very reassuring. In addition, there was no WiFi or entertainment available.

The worst experience I've ever had because the "people" @ Avianca wouldn't let me fly because they said I needed a round trip ticket

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

Not good, tried to purchase a first class upgrade and they couldn’t get it done. Was super uncomfortable the whole time.
