Very courteous staff. Abnoxious passenger in front of me who reclined her seat all the way without warning and without considering the person behind her. My flight ORD-WAW was so much more pleasant because of the courtesy of the passenger in front of me.

Very courteous staff. Abnoxious passenger in front of me who reclined her seat all the way without warning and without considering the person behind her. My flight ORD-WAW was so much more pleasant because of the courtesy of the passenger in front of me.

LOT told me on my first flight that I had missed boarding my second flight and told us to go to a service desk to reschedule. We then were told our flight was still boarding and that we had to run through the Warsaw airport to catch it which is just a long long runway airport. The workers at the airport were not helpful at all and you have to go through two passport checkpoints. I have asthma and was almost dead when I got on the plane and no one helped or gave us water or even acknowledged us. The flight was fine - the crew members are not friendly so it’s a very functional flight at best. Also my bag didn’t make it to my final destination.

LOT was very disorganized at Istanbul airport with no communication with travelers. Our flight was delayed over and hour and a half and there were no announcements, displays or anything about it. It almost left me missing my second flight!

Once again very friendly helpful staff A short flight but not only on time actually a bit early

I would like to be able to choose the seat before the flight without paying extra money. Family members should not to be separated from each other.

Everything was very good. I felt that the value received in paying for Business Class tickets was very good. The entertainment offered was plentiful, but could be improved with more recent options as well. By no means a deal-breaker. The staff were awesome, in the airport, at the gate and onboard.

bus ride to the plane was very crowded and had to wait a long time to get to the plane. The flight itself was great.

The airline wouldn't let me take my stroller to the gate, even though the website states we can. My screen did not work. Their website also states that long flights offer wifi to be purchased. My 8.5-hour flight did not have wifi available. I pushed my call light to ask for water (I was willing to buy it). It took over an hour for them to come and they could only give me a small glass at a time. Waters were not available for purchase.

Flight was delayed by a hour could have been better addressed. Flight was fine with great service by the flight attendants

They broke my luggage. I’m pissed off about that. Service was slow and inconsistent.

Because of a thunder storm in JAX we spent more than an hour on the run way in the aircraft. The crew did not even offered water to passengers.

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

Biggest gripes were that the seats were extra narrow as the 4-in-the-middle taper down. As with most flight, too little leg room hurts my aging hips. Also changing the flight time to 3 hours earlier meant that we had a terribly long lay-over in one of the world's most boring airports

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

Absolutely the most awful experience in the history of service from gate agents to baggage handlers. Never will i use kayak or Lufthansa again. Ever.

No internet, very narrow seats insufficient room for three passengers with encroachment.

Absolutely horrible HORRIBLENE! United airlines failed on every front. My trip was silosem to takę 17h nad endem up takimi 47h! I was treated poorely and I wasn’t reimbursed for all the problems.

The flight was more than an hour late. We got locked inside the gate area with no information whatsoever, no way to get out to get some food. Lufthansa was, again, really disappointing

Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures

Give at least coffee or juice as it is an international flight.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They took good care of me on the plane and had it not been for handicap assistance I would definitely had missed my connecting flight . Not BA fault but The airport security instead . Two hours is way too long for security

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

old seat need to go! outdated and uncomfortable. I waited 40 minutes for my bag

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced

I paid for luggage when I bought the ticket but I could not board until I paid for luggage again. The fault lays at the feet of eDreams, the company that booked our flight. Sorry, Air Serbia, but it did affect the boarding process.

They had lost my ticket and despite showing them the confirmation email with the itinerary and receipt of payment for the flight they could not put me on that flight and rescheduled departure postponing it by a whole week

Kraljevo is very convenient airport. It's brand new, small.and efficient. Great job!

Long delay (6 hour late departure, not informative enough to provide up to date info on flight, poor food quality

Plane was late causing me to miss connection. Flight the next late causing me to miss the rebooked connection. Air seberia I think is more late than on time

Plane was old. Seats were hard and very close together. No in flight entertainment.

This was my connection flight that was moved time ahead for a almost entire day so I lost it and I had to purchase new ticket once I landed in Copenhagen since nobody wanted to take responsibility for moving flight in that way so it’s impossible to make it. Very poor job by Underpricer, Air Serbia and SAS.

I purchased an exit row seat and priority boarding, about 3 months in advance. Without any communication whatsoever, my seat was moved to row 2, when I checked my reservation 2-3 days before departure. As no exit row seats were available anymore, I selected a seat 1C. However, once at the airport, I was issued maybe the worst possible seat, 29E, middle seat, one row before the last. It is not worth my time to request the refund on the ancillary purchase, I am simply done flying with Air Serbia. Also there was no boarding process to speak of at all, or online check in.

Lacking online check in, had to wait an hour in order to check in on the counter even without language.

This flight was better, plane was newer and didn’t have broken parts. Flight crew was very attentive and friendly.

It’s a budget airline. You get what you pay for. They insisted on getting us out of the gate and into our slot on time. They got us to the destination safely. Aircraft was clean and well maintained. What more could we want

Half an hour delay. Squeezed into a small Departure Lounge with very few seats. Noisy flight with screaming unruly kids. Loud IPads and Phones. Heaven!

Were delayed in the airport for 5 hours with no explanation. Flight kept getting delayed by an hour at a time and wizz air staff were no where to be found

The flight was delayed 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.

It's a budget airline. Great for short flight. Smooth landing.

4 hr delay and only told less than 2hrs before. Only given water and nuts on the flight as complimentary service. Left to wait in rain before boarding.

To be honest I did not like anything. Communication to why my flight was cancelled mid air 2 and half hours into my flight. Customer service desk were not helpful with providing information or a solution on what can be done.

I have been treated unacceptably by WizzAir aircraft crew in a previous flight, they threatened me and abused me, and I received an OFFICIAL written apology, but only two (2) months later. This flight had no such unacceptable behaviour, but it's not nice to be left waiting in the walkway (from gate to aircraft) for a long time, just so that the 'boarding' appears to be early, even if actual departure is not.
