Very good flight crew and very nice people staff were incredible especially the gate agent

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

The flight was delayed for about 2 hrs. Other than it, it was good.

Advertised fruit trays with cheese, but only snacks handed out!

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Great. I had to modify a flight. That was easy and free. Thank You

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

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

Simply as follows:- First, there was no vegetarian option for the meal Second, only 2 washrooms for the entire economy class.

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

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

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

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

Very happy with my flight. I would definitely recommend it.

Did upgrade, travel in business it was great (more room I could sleep)

Not United Airlines' fault. It's ORL airport's fault.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

They did the one thing that really matters - got to Chicago early.

I liked the snacks and the flight attendants were friendly.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

Flight was late - I was downgraded from first class to coach

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

I don’t know who decides what food to serve on these flights but I would be so embarrassed if I served this to anyone and call it food…

For whatever reason, the flight was not catered -we were told it would be a 45 minute delay waiting for catering - so no food. There were opened candy and peanuts in the seatback pocket. Flight landed early in DFW but due to the assigned gate not being available, we sat on the ground for 30 minutes waiting for the gate to open - making the flight actually arrive at the gate late.

Not great. Booked Extra seats and got nothing extra at all. It’s basically a big budget airline.

The pilot greased the landing and the crew was fantastic.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

delayed due to weather. Could not communicate with family since the wifi was broken

Experience was good, however I had a delay due to weather happening and had to re purchase a seat on a new plane for a higher price (could be my own issue and misunderstanding) but other than that situation. First time flyer (by myself) was terrific!! The last from ORD to ALO didn't have wifi, but it was only 45 minutes so I'm sure that was part of the reason. Overall my experience was great! Next time I will remember to buy tickets with longer layovers. The delays really saved my overall anxiety. :)

Pros: we leave and arrive on time Cons: the most uncomfortable seats ever. You cant recline at all your seats. No entertainment No TVs flight attendants didn't provide even a glass of water. You have to go to back of the airplane and ask for one. I am Colombian and I remember seeing the flight attendants very neat, elegants which is or was a staple of Avianca.it was one with tennis shoes, no male up, the hair was messy... that was really odd.

Here we have another airline flying to Guatemala but doesn't have a plus or a less, just in the middle. Why? Well, first we don't have even free water Movie selection is poor Seats don't recline in some places Food selection is carb based Forgot to mention, customer service on the web is the worst. Good things; Very reliable on schedule Kind crew

Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

We waited for one hour to deboard the plane after landing. That could be better

I like the crew they're very friendly. I don't like. on five hour flight they not offered snacks. Any drink. Not even coffee

Not even water is offered on the flight. You cannot lean back on the seats and the seats are so narrow you can’t avoid rubbing elbows with the person next to you.

I couldnt recline the seat. Other than that crew was very attentive and helpful. Thsnk you

I had to go to the boarding counter for them to enter my return flight as it’s not with Avianca. There was a long queue as there were lots of people being called to the counter.

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.
