Crew was excellent. Comfort seats not as nice as other kinds of planes.

Not a "Delta" issue, but a JFK issue: We booked a connecting flight with 3 1/2 hours between to clearn immigration and customs. Our inbound flight (BCN to JFK) was on the taxiway 45 minutes which ate into our layover time. Immigtration was insanely quick with the CBP MPC app; however, clearing TSA (again, after we were ALREADY cleared in Spain on the inbound international flight) took over 95 minutes. This left us with 10 minutes before boarding the connecting flight (JFK to SAN) to walk to the far end of Terminal 4 and try to find food. We didn't find any food that could promise to serve us in under 10 minutes so we boarded the Delta flight after coming off a plance and an 8-hour flight knowing that we wouldn't be served any food on the next 5 1/2 hour flight. I feel like Delta needs to put pressure on the JFK TSA to open more screening stations (by our count, we saw only 5 scanners open and a line of - as we said - over 90 minutes. The insult is that we WERE ALREADY SCREENED through TSA, but as you come off one flight into the USA, you have to go through the whole process again. It seems like if you have a connecting flight, there should be a way to pass through immigration and customs without needing to return through TSA.

The way BCN airport handled boarding was a huge improvement over our trip to Spain from JFK. Instead of gate-mosquitos edging in before their zone was called, in BCN they had clearly marked lines for Zones 1-8 and people just lined up correctly. The flight itself was uneventful. The meal (curried chicken and rice) was one of the better meals we've had on Delta. Entertainment options were plentiful, power chargers were available in Main Cabin, and seats were decent. Flight staff were very friendly and positive throughout the 8 hour flight.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

The checkpoint hornets are always looking fhrough Americans' luggage keeping what they deem impassible! Grrrrr!

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2

Flight was an hour late, who knows why. It was OK, nothing outstanding.

Only not having an assigned seat was an issue. Rest was great

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Had to go through security at the gate again. Had to take off shoes and go through the whole thing again even though we have global entry. They asked us to check in items bought at duty free during our layover and since we checked our luggage at the original departure airport, they forced us to check in a small backpack. None of this ever happened with other airlines. In addition, no vegetarian food option and no snacks during a 7 hr flight. Luggage limits are unusually small. This is unacceptable. Will NEVER fly Copa again and will tell friends and family to avoid this airline.

We paid extra with copa for seats near one another The plane was changed and we lost our seats We were all Separated. We have not received a refund for our seats despite emailing and calling.

We had a five hour layover in the way home from Colombia. I read the "bout your flight" email carefully before we checked bags. We had to go through security right at the gate. Almost lost our ground coffee because that airport only allows 16 ounce of coffee and we had 18. I've been to 48 countries and never heard of a coffee restriction. I can't follow a rule I don't know about. I requested they bring our coffee to our checked luggage. Instead tey gate checked our bag for free. Back to planning transfers in Dallas I guess

Tell people to remain in their seats during the meal/beverage distribution. Enforce boarding by group numbers. No one was checking. Tell people to turn their electronics speakers off. Bigger cups for drinks.

There was no individual at the front check in when I arrived. I waited for at least 15 minutes and walked around asking security/janitors if they could help and they did not have a solution. So I had to take my checked bag through security and they threw away some of my items. I ended up making it to the gate only a few minutes before it closed due to my waiting for an agent at check in.

We were in transit from Lima (flight at 1.10am) and we were in stand by in our flight from Panama to Washington. We wait from 4.30 am to 18.30pm in the Airport. The company give us 2 x 15 dollars for eat during the day and a personnal travel voucher of 400 dollars each. Do they buy food one time something in the Airport ??? And one of us live in France so the voucher is not usable. More than 24 hours travel !! And our place were near the toilets, with 8 children around us. The boy behind my seat stamped his feet on my back all the flight. Really Wonder full ! So we are totally unhappy with our travel. Thanks Copa Airlines....

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

No headphones given for inflight entertainment. I missed my flight from the previous day and the customer service agent tried to extort an additional $100.00 US from me for missing my flight. Really?!

Great from check in all the way to the end. Very happy with Copa

Copa stranded us ans then tried to charge us thousands to leave Panama.

We had a very long diversion and our food voucher didn’t work because the restaurants were closed

United airlines, mediocre at best. No issues , nothing great . Worked for me

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

Very nice and clean plane. Transit time between flights was tight though

Mostly the experience was good except for the flight changes made by UA which meant longer layover in DC

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

United left one of our bags back in SFO but that’s not my real complaint. The complaint is how it all went down. So we checked in the day before online and were told we could use the quick drop for luggage. So the next day I used baggage quick drop curbside at SFO. The agent mistakenly didn't tag my bag as he put my bag on the conveyor belt untagged. We immediately alerted him he had not tagged the bag. I walked with him to the baggage service office to find my bag and tag it. We waited outside the office for 10 mins. He came out and said everything was ok and the bag was going to be tagged and on my flight. We received a text that one of our bags was on the flight but the other was not. I alerted my first class flight attendant immediately upon boarding the flight. She was helpful and said she’d get it sorted out right away. She called over the gate agent. The gate agent used my bag number and looked over information on her device. She said my bag was on the flight. The flight attendant was standing with her, looking at the device, and also said “yep it’s on the flight”. During the flight the flight attendant made reference to how reassuring it must feel knowing the bag was on the flight. Upon arriving to IAD we received a text that my bag was not on my flight. The text said my bag would arrive to my final destination LIS 24 hrs late. I understand that mistakes happen. I was totally ok with my bag mistakenly not getting tagged at the quick drop. I was fine with walking down to baggage services to tag my bag. But, what I am not ok with is that the United staff said they fixed the mistake two different times, assuring me twice that my bag would be/was on the plane…and it wasn’t. I expected better attention by the employees, for them to do what they said they were going to do. We also spent extra money to upgrade our seats to first class, including the entire return leg from Lisbon to San Francisco because we wanted a smoother and more relaxing travel experience. Our money was not well spent. We will not be using United for travel going forward.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Horrifying! And I am almost 2 million miles with United. Late by 3 1/2 hours. Worst: after two hours on the plane waiting, they decided that one of the tires had been damaged and then decided to change it. Another hour and a half to change the tire!!!!! NO EXCUSE FOR THIS. The crew didn't even offer a glass of water until we had been on the plane for FIVE hours. This is the worst airline in the world. I'm simply stuck because they fly on the only routes I need.
