Pros: "Kosher snacks! Thank you. Screens and outlets at every seat. Safe, controlled Covid protocols including de-boarding. Excellent!"
Pros: "Delta flight took extra precaution to keep all passengers safe before during and after the flight. They communicate effectively during the flight. I will be flying Delta again and again."
Cons: "The trip was great"
Cons: "We arrived around 39 minutes early and the whole process was very smooth"
Cons: "I would ask that the gate does not share in detail reason for delay in seat assignment is related to getting a family sitting together when the basic rules should apply unilaterally."
Pros: "Got to my destination without any issues"
Cons: "Seats/seating area are too small, and I'm not a big person."
Cons: "First class seats were too close together. It was very difficult to get out of you seat into the aisle. Food was not what it should have been for 1st class There was no wall between 1st class and coach giving little privacy when I worked my laptop. it was in direct view of the middle seat in coach"
Pros: "Crew was nice and welcoming"
Cons: "Well, if our plane had been leaving on time it would've been superb."
Pros: "N/A"
Cons: "Chinese Eastern did not try to help and solve my problem."
Pros: "The service is very good from the beginning. The flight attendant is very caring thanks so much."
Pros: "There was a bit of a mixup in boarding the plane but otherwise the flight was good. There was no entertainment system on this short flight. The flight attendants were very pleasant & efficient. They only served snacks on this short flight but were very good at ensuring everyone had at least one or more beverages. The premium seats were very comfortable ."
Pros: "The crew was fantastic and plane was clean"
Cons: "My entertainment video player had a bad earphone jack so i could not watch movies or tv and resorted to paying for wifi"
Pros: "Really easy boarding and flight. Great in flight entertainment options."
Pros: "Flight attendants were friendly and thoughtful."
Cons: "Seating is too tight. Hard to believe that in 2019, major airlines still have seats without any electrical or UBS outlets for charging devices."
Pros: "Crew was great."
Cons: "Plane was about 1000 years old and I don’t think I’ve sat in a more uncomfortable seat."
Cons: "I was apparently "flagged" by British Airways for extra security checks. As I understood it in London, I was randomly selected for this security check. This then apparently meant that I was to be flagged for all subsequent flights. This meant that in Chicago, after going through two other security checks that day (Zurich and London) and completing customs, I had to engage in a full Homeland security check. This involved removing protective covers from my laptop and phone that were hard to get off (not meant to be taken off regularly) and a full body search that I did not have to do in London. After many hours of traveling, this was very a frustrating experience."
Pros: "Flight crew was great. The plane was half full, so the attendants allowed us to move."
Cons: "Terrible landing in Charlotte. The plane was rattling and had an annoying whistle."
Cons: "British Airways/American Airlines lost/delayed luggage again! Then send an email in the middle of night with a link to schedule home delivery of the luggage that was valid for 4 hours only. It is clearly an attempt to cheat out of their responsibility of home delivery of the luggage that was delayed the second time. Poor, poor service by American Airlines."
Cons: "Flight was delayed for more than 4 hours with little communication from staff as to why, gate was changed to a gate across the airport."
Cons: "Three + hour delay out of ORD, equipment problems. Even though she had a boarding pass, they would not allow wife to board. Some ticketing problem between AA and BA. Finally, they let her on. We were the last to board."
Cons: "On my first flight from SLC to ORD I asked 3 different American Airlines employees if I needed to pay for my carryon before I got on the plane. They all said no. I got on the plane, put my carryon under the seat in front of me and everything was great. I landed in Chicago, got to my gate, went to board and this very rude employee stopped me after I scanned my ticket and told me I couldn’t board with my bag. The EXACT bag I had boarded with in SLC. After harshly grabbing my bag and putting it in the carryon basket to check for size, she wouldn’t let me pass by her into the boarding bridge and told me I was going to have to pay. I tried explaining that I had asked I’m SLC if I needed to check it and they had all said no and that it fit under my seat. She said, “I don’t care what they said in SL, this is what I’m saying here.” And directed me to the front desk where I had to pay $50!! $50 for a carryon backpack that fit under my seat comfortably 20 minutes before!! Without saying a word (cause I didn’t want to yell at the poor girl behind the desk) I paid the $50 and proceeded to enter the bridge but before I passed through, the rude woman said, “have a nice flight ma’am” and scoffed!! An audible scoff. So I’m short, I hate American Airlines and I will do my BEST to not have to fly with them in the future."
Pros: "My favorite part of the flight was our on time departure! :-)"
Cons: "I don't care for the configuration of the Airbus 320...it's rather difficult to adjust the overhead light and air, compared to the placement on a Boeing 737."
Pros: "Flight attendants were absolutely amazing!!!!! They made the trip very enjoyable!"
Cons: "Food!"
Pros: "The flight was late and barely made the connecting flight. In the end, my luggage arrived damaged."
Pros: "I like flying Lufthansa for entire trip then changing to united airlines"
Cons: "Particular everything the airline"
Cons: "I missed having the navigation map when traveling such a long distance."
Pros: "Once the flights took off, everything was just great."
Cons: "The boarding process was awful. There are zones, but they are all boarded simultaneously. What's the point of paying to board early if you don't get the chance. Then, I had to check my bag because the boarding order was a mess. One flight attendant tried to force me to put my bag overhead when I told her I could fit it under the seat. She stressed me out unnecessarily."
Pros: "The boarding and seating happened in a timely fashion, and the crew was courteous. The lunch meal (I had requested Asian vegetarian) wasn't amazing, but not as bad as it could've been."
Cons: "The flight was not with Lufthansa, but it was actually through United, which was extremely confusing as I did my ticket confirmation, seat booking and meal choice through Lufthansa prior to my trip. To find out on the day of the flight that I had to check in and go through United was extremely annoying, as the counters are in different terminals and it was unnecessarily stressful. The flight itself was crammed, with absolutely no leg space, and not even enough space under the seat to stow my backpack (which had fit perfectly on my Brussels Airlines flight to Madrid). I had requested the Asian vegetarian meal, and the snack we got prior to landing was pretty much two slices of cucumber on a small bun (and an apple on the side) - extremely dry and hard to eat. I asked for mayo, but the flight neither had that, nor any other condiments to make the "sandwich" more edible."
Pros: "Flight delayed- missed connection. No easy way to get Home to Vermont. Flew to Boston and rented car!"
Pros: "We liked the crew, they were helpful."
Cons: "We did not like the video on the United flight that used the app. We were not told about this until it was too late and the instructions were not good for how to get the app--they were misleading. I had to go to the app store, not the United website. Also, our seats were changed without our knowledge and the flight description for the flight from Austin to Washington, DC, specified complimentary lunch and there was no lunch unless you wanted to buy it. This should be more clear, so that I can bring my own lunch if there will be none provided."
Pros: "Again- nothing"
Cons: "This flight was canceled for me! Why am I being asked how I would rate it?!"
