My flight experience was generally good, but the boarding process was stressful. I was pulled out of line at the gate during the photo ID check, and after being cleared, I was never given an explanation for the delay despite asking for clarification. This lack of communication was the only downside to an otherwise smooth trip.

This lack of communication was the only downside to an otherwise smooth trip.

The flight was delayed and knowing I was going to miss my connection, nothing was done proactively to try and get me rebooked. It was an act of congress to do so. This is not on the crew, but on the experience itself

Your survey needs a N/A option. I didn’t use the entertainment or eat food.

Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.

Flight was delayed multiple time and for more than 1 hr. My onward flight from BOS to MCI was also delayed. These delays have caused me so much inconvenience and Delta does nothing to ensure flights take off on time. No one knew why the inbound flight was delayed and what was the issue.

Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

This is the first time I've been disappointed with Delta. I was called by Delta to see if I would volunteer to change flights since my original flight home was overbooked. I accepted. The modified booking only provided me a 35 minute layover - when you subtract the fact that boarding closes for a flight 15 minutes early, that gave me 20 minutes to run for one end of the airport to the other. I barely made it. On the 2.5 hour flight to Tampa, the crew repeatedly let us know over the intercom that they cannot serve drinks or snacks due to safety/turbulence. I would have accepted this reason if they did not CONTINUALLY SERVE DRINKS AND COOKED FOOD to First class. If safety is the excuse then the entire plane should be strapped in for safety. On top of this the air conditioning vents were not working correctly and the plane was uncomfortably warm. I love Delta and am a loyal Delta traveler, and I have never had an experience like this. I don't know if there's a disconnect between availability among third-party sites like KAYAK and the airlines or what, but when overbooking causes issues like this for travelers it should be reviewed and changes to the booking process should be made. I blame BOTH KAYAK and Delta for this terrible experience.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

Perfect. On time and the weather was perfect so we came in a few minutes early.

Upset about cancel to St. John’s and no overnight accomodation

Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Entertainment kept turning itself off. Gave up on watching a movie.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Fine not above and beyond as I had a connection that was delayed due to maintenance

Boarding was quick and efficient. My screen didn’t come on and everyone else had theirs working so a little bummer but it was a short flight!

They makes us feel confident on the flight. There was no any cancelation and they are really helpful with us.

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

West Jet flight was cancelled and I was not notified. I found out when I tried to check in on-line. Spent 4 hours on the phone with West Jet and Just Fly trying to figure what happened.

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Flight was on time. Online check in capabilities made things quick and easy. Zone boarding was enforced, which I appreciate. Everyone was not lining up ahead of their zone being called. Crew was professional and friendly.

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

Trip was uneventful which is good. Boarding took a long time due to many disabled/elderly requiring assistance which again is fine. Landing and take off were excellent. Food and entertainment were as expected, bring your own if you have preferences otherwise you get what you get.

Okay but not like typical first or business class. On domestic airlines

I liked the kindness of the check in counter crew, the flexibility with changing seats and the comfort. Better free drink selection would have been good but it wasn't a long flight.

Flight was on time… crew normal experience… captain was informative. Boarding at the gate had a bit chaotic ,but overall, it was an enjoyable full flight and I thank you as it was my first time flying Westjet and I will do it again. Regards

Limited service due to turbulence, N/A Food and Drink. No entertainment

Staff in first class seemed to struggle to provide service to both sections. I didn’t get breakfast though I requested it. I only got coffee after asking the opposite side flight attendant and then could never see them to request a bottle of water.

The plane was delayed after we boarded - although they sent an email to my work email (which I did not get until later) there was no announcement from the PA about the delay in flight. Fortunately, they made up the time in the air and we landed around the original time.

My luggage is missing. I haven’t received it. No one seems to know how I can find it

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

I very rarely fly American and my experience today reenforces that is the correct decision. While the staff were all very courteous, our flight was first thing in the morning so there was no reason to be delayed, yet appropriate maintenance checks weren’t completed prior to our flight so we were delayed multiple times. Not a great showing, American Airlines.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Was a normal flight but it was delayed, and there wasn't an explanation.

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Boarding was disorganized and delayed because they overbooked and wanted people to give up seats then further delayed due to an issue with the plane. They did not load my bag and it took a day for them to return it. Flight attendant was lovely and the only positive thing about this trip.
