Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Don’t know they cancelled the flight day before I was to leave. They sent a email at 9:00 pm at night saying they cancelled. That is the smooth way to say we don’t want your business! I think they didn’t have enough people booking so they cancelled the flight! It’s all about the money anymore there is no honesty in business.

Having to reschedule flights a day later, they loaded by luggage on the wrong plane from Little rock now I have to HOPE they deliver it to where im staying like they said would. International flight crew was very disgruntled and not very friendly.

We will be writing a long, detailed letter to corporate about our awful experience with American airlines.

It took way too long to diagnose and solve the problem of a broken crew member cabin seat. Though compensation for the volunteer who left the flight was very kind.

The entertainment package was vast and the selections were very current. Keep updating it was great.

I like the web site, prompt notifications, website checks in process, and airport check in. The flight attendants are attentive and polite. The return flight was 2 hours late and reason vine doesn't sound like an unplanned and unexpected issue (scheduled plane maintenance).

Our flight was delayed almost 3.5 hours (some of the issue seemed to be weather-related, yes) but NOTHING was offered as an conciliatory gesture for this delay. No food offering or any additional drink offering. There is no entertainment is available on any screen behind the seats. The airlines are so quick to penalize customers for slightest requests for comfort- seat changes, complicated baggage allowances, seating zones which are utterly dehumanizing (ZONE 9? after Zone 4- why? This is so clearly meant to be a message to those that do not have 'loyalty' to this airline to make a distinguishing line in the sand. There is such a lack of humanity in the way people are corralled in and spoken to. So, I don't think airlines should be all that surprised when those some dehumanizing corporate treatment is returned to them when asked. The flight on the way into Calgary was scheduled to arrived at 9:25 and we arrived at 12:45 AM. It is not okay. I would think TWICE and possibly once more before booking with them again. Their overhead bins are small and limited so they bully you into either paying for a $90 checked bag or gate check a lot of people's bags. Often on their website there is no carry-on bag allowance. Beware!

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

They were on time and everything went as expected. The only thing that could be better was they didn't wait for us to get through customs to pick up our luggage off the carousel. An employee picked it up and was shoving it together with others onto a cart. Later we found one of our luggage was slightly bent.

Delayed boarding. Delayed taking off. Delayed landing. Missed our connecting flight. Our seats on this plane were not assigned until last minute, splitting up our family with kids. I sat in the last row next to the bathroom with so many people rubbing up against me to get to the bathroom the entire flight.

Another delayed flight. Then got bumped to a later connecting flight, over two hours later! Plane was hot and uncomfortable.

Asked to cancel flight 6 days in advance of flight back to St. Louis, MO. Would not allow. No credit either.

Crew was nice especially by North American standards. Bad good. No entertainment screens. Terrible WiFi

Not only was the flight delayed more than 3 hours but also there was no internet or movies on the flight. It was Flair/Spirit quality of experience at Westjet prices

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.
