Get to the airport at least 3 to 4 hours ahead -- the lines are long, and so are the walks to the gate.

Be aware that checked in bags are EUR70 per bag. You can board the plane via stairs either at the front or back. I thought the experience was ok a 13 hour flight

The AA website states that the cost for luggage is $45 for transatlantic flights. Encourage them to call for the actual cost as I was charged $70EU for each bag.

Check in online if you must fly this airline. Avoid excess weight (up to $250 per bag!). Better yet - fly another carrier. Single worst flying experience of my life. And I easily fly 150,000 miles every year with all types of carriers.

Check to make sure the airline you are booking through is not subcontracting it out to a janky airline to cut costs.

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

If you cant travel Delta One, Comfort Class is the next best thing!

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Service was professional and quick. Premium economy seat was comfortable given the class

I'm a United 1K member and have ben for 10 years. The gate agent had no control over the boarding process and had us passengers queued for hours as delays were announced. On the plane, the overhead air nozzle was broken so col over was powering through on me and the passenger next to me. Not a great experience for a million miler on United. Feel free to contact me. Josh Smigel - DM426089

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

I missed my flight and had to buy new tickets Rome- Boston

Worst flight I ever experienced, what was supposed to a 7 hour flight ended being 13 hours on a plane with no ac and the worst cabin I have ever seen. Never again.

Excellent plane, 787. Very good seat and additional stuff they provide. Good food. Very good staff.

Excellent except WiFi is a Must on Biz class 10 hour flight ! Didn’t work entire flight. SW doesn’t do that.

Excellent crew, food and service. Boarding via bus is always a pain but overall really good

Stewardess was not attentive at all asked for a bottle of water never came by 15 minutes later I asked her she said that she forgot there was only 12 people in first class and two stewardess unacceptable I ordered the fish was the last person to order. They said that they did not have any had to have a different item pasta at the inside of it because I was diabetic. Worst experience I ever had will never travel this airline again.

Very nice staff, terrible food, not very comfortable premium economy.

Boarding, crew, food and baggage handling excellent (no bags lost, yay!). However for an 8 hour flight, there were limited entertainment options. And really would have liked to have a pillow!

The crew was super friendly and helpful. The food was quite good. An overall positive experience.

A more organized boarding experience and better food would have made the experience better.

why can't planes be boarded from back to front?? everything was great otherwise

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Never took the flight due to strikes which happens but there was no timely coordination to find me new flights. I had to call Lufthansa and Kayak support only to be given no good options and a 75% refund. Ended up spending way more for alternative flights that I coordinated myself for a trip I had booked 6 months prior.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time
