I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Aside from a completely packed plane, I really have no complaints.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

The Check-in process at CDG was confusing and the crew was not helpful. But the flight was on-time and that is most important to me.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

I’m considering never flying with Iceland Air again. The seats in economy are torture. Now you only get water, coffee and tea for free- really? No food, not a single peanut. The passport line was insane, everyone was worried about catching their connecting flight. This was the third time I’ve barely made my connection, had to run. It can’t be that my choice is to use the bathroom (during the 50 minutes between flights) or make my flight. SO stressful! Ugh.

Iceland Air severely damaged a checked bag. Additionally, the gate agent caused issues for many passengers who had standard-sized onboard bags that would have passed inspection by any other airline.

Nice, quick flight. There were lots of empty seats so they told me I could sit next to the emergency exit where I would have more legroom.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.

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

Parents with permanently crying baby on board. Neither parents nor crew did anything to calm the baby. The food was extremely disappointing. Seafood stew was very, very small! Not even appetizer size! Seat had a gap in the back. Had to use a pillow to fill it.

Food choices limited & not enticing Seats quite uncomfortable & difficult to control

Definitely get premium economy on a flight this long if you can. Your legs and while body will thank you.

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

I upgraded to the business class cabin. It was the poorest business class I have ever experienced. No access to any business lounge in Tampa airport. Seats are not comfortable. I had a window seat and had to step/crawl over the next seat. Food was mediocre and service below average for business class. Bathroom location was ridiculous. No place to wait. I cannot believe I paid this kind of money and will never fly Lufthansa Discover again. They really should reimburse me somehow.

Boarding was disorganized. The door to one to the toilets wouldn’t lock. The plane was shockingly cramped, and clearly used for domestic flights due to the menus for items to sell domestic travelers. United should be ashamed of its small seats, tiny unclean toilets, and money grubbing stance toward services, compared to Lufthansa, Emirates, and most international carriers United is awful.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

24 hour delays aren’t even heard in 3rd world countries with archaic transportation systems. I’m never flying American Airlines again.

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.

Canceled flight late London to Florence. Help at airport very poor. Treated poorly. Had to sleep in the airport. Lost bags- still do not have them. Horrible. I should be reimbursed!

The seats are extra cramped if you are taller than 5’8! Spring for the extra legroom seats for sure if you have a long flight!

Very disappointed with British Airways. It has been over 24 hours and I still have not received my checked baggage or any proper update. Customer support has been unresponsive, making the situation even more frustrating. Poor baggage handling and lack of communication seriously impacted my travel experience.

All the above categories was great. Seats entirely too cramped.

Flight was good but temp in the cabin was cold.

Departure was delayed leading to late arrival, 25 min wait for a gate. Basically, missed all our connections & had to be rebooted, which was a very long process.

I like American Airlines and their safety record. They provide quality service and a feel safe enough to prefer American Airlines over other carriers even if I have to pay a little more.

Good flight, no turbulence. I felt safe and comfortable which is really important when I am just a passenger.

It’s a budget-friendly airline, so expect smaller meal and snack portions and no free alcohol to drink on international flights. Airline food is never exciting in economy class, so I always plan on taking my own food and snacks- and I don’t consume alcohol, so no complaints from me! Flight attendants were friendly, attentive, and helpful. The airplane was newer with USB a+c charging ports, massive infotainment screens, and a lot of entertainment media to choose from. The airplane seats are less padded than other airlines I’ve been to, but the benefit is that there was more legroom because of the thinner seat profiles. Honestly, more legroom gave me more comfort than having more padding on a seat (which just gets flattened over time and repeated use) Overall, I really liked my Condor experiences (4 different planes) from LAX-Frankfurt-Barcelona and back. I would not hesitate to fly with them in the future, if the prices are lower than other companies

They made us walk thru entire Frankfurt Airport, which at this age. With very less time, we had to run. It was unacceptable.

They answer the phone promptly. Crew is friendly and they work efficiently.

I flew premium economy. My only complaint is the size of the bathroom. I am 6’2 I. Tried to rush my teeth in there and ended up getting toothpaste and water in my pants. And the only way to do it was by sitting on the toilet

My flight was delayed twice. It finally left 24 hours later. In addition there were conflicting messages between kayak and condor that made the experience worse.

Upgraded to premium economy at the gate. Well worth it!

The flight was canceled and airlines did nothing to accommodate the passengers. After few hours they booked me randomly on a flight that had long layover and didn’t provide any compensation or effort to help. The crew was rude, no representation on the airport. Everything needs to be on call and agents there had no knowledge or control. For everything, they were like we can’t do it and you need to file a claim later. That was not helpful at all and will not make my travel experience any easier. Very disappointed in their service.

Great plane and flight attendants. The person next to me had a DISGUSTING smelling mouth and breath, so that was nasty to deal with the whole flight. Brush your teeth, people! Condor was amazing, though :-)

It would be nice to have a cleaner facility, it was hard to access it. It was always full of people working in that space. The covers and especially the matt of bad quality and old. Many times reused. I would not use it. Food: the bread rolls were old, and food had strange choices. Chicken was terrible.

There was some nice staff when I entered and left, but the thrre flight attendants who served us were very brusque and rude. I have celiac and when I checked in, I tried to find the option to make sure my meals (stick on a 10+ hour flight after a 3 hour flight and short layover) were gluten free because I didn’t have time to get anything. Couldn’t find the selection for it, and every part of the meal and purchase options were gluten, so I didn’t get to eat. During check in the allergies section should be easy to identify and check so this doesn’t happen. Having more options for gluten free at this time should be easy.
