The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

The table at my seat was dirty, the crew was nice, the boarding was swift. An average Ryanair experience but this time the plane was not properly cleaned between flights.

After passing through boarding gates we had to wait for 45 minutes in a small space with no place to sit.

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

On time boarding, on time departure and early arrival. As it should be. Yes, the comfort and benefits are very poor, but therefore the ticket is 6 times cheaper than with a flag carrier. So I am not complaining about it. You get what you pay for.

They lost a bag and now our vacation is ruined

If you buy a cabin luggage, but don’t need it for your kids, so you will end up with mixed priorities. And you will need to use non priority line

Boarding was by group and we had to take the bus. There were no elevators so had to walk down the stairs. It would help to have escalators or elevators. Note I had a special needs child and the gate crew was rushing us in. The bus was full but we were packed with no seats to sit.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

What could have been better was holding the flight when our ORD to FRA flight was a bit late. We sat at FRA for 7 hours. It takes time to go through passport control and to get to a gate at that very large airport. We went as fast possible to our gate but were too late. Cityline is a good provider other wise.

I don’t understand how they charge as much as they do for such a poor experience

Everything was on time, even though the layover in Frankfurt was 22hrs

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Booked seats (paid extra) online and found they didn’t exist on the flight. We were then separated from the rest of our party. Given seats in the very back of the plane. We will not fly Discover or Lufthansa again. We will not book flights or travel through Kayak again!

Had a few open seats and could use it for a great rest ful journey

Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.

Typical wizzair flight, nothing special , but as there were flight in the evening we got sandwiches with 50% discount. Terminal wizzair is using is awful. Separate from normal airport, no duty free and only one cafe. Also was late for more than 2 hours but we didn’t got any food or water vouchers.

Timely departures and arrivals. The seat was slightly forward leaning which made it uncomfortable

Flight was delayed by two hours and we then sat on the runway for another 40 minutes and circled Gatwick twice making it 3 hours later landing this is very poor compared to all the other operators I’ve flown with the outbound flight was an hour late

There were not enough staff and signage to direct people to Wizz Priority lanes for check-in and boarding. It didn't feel like we were Wizz Priority holders.

Had to pay £45 to check in at the airport because I didn't check-in online at least 3 hours prior... and it wasn't mentioned on the booking / App (online check-in is only marked as "included service"). Upon landing, captain failed to land the first attempt and had to take off again for an re-attempt. Overall mid experience, would definitely pay a bit more at first to avoid this again.

Two of our boarding details were missing and they wanted to charge us 84 pounds for that, although it was totally their fault

They boarded us despite knowing we wouldn’t be taking off for another hour and boarded us into a plane who’s air conditioning was not working properly. So we were sat in a hot plane for an hour with no access to the bathroom getting hotter and hotter. A little bit of communication between the teams would have avoided this.

I planned to be working during the flight but next to and in front of me there was a family (basically all around me) who had screaming kids all the way long and they were rude and the kid was kicking me as well and constantly wanted to grab my phone etc. I was so pissed, I didn't think they will travel priority so I didn't think they'll sit next to me but they did. I asked the crew if there is a chance for me to go to another seat far away from there...And they were so kind, immediately after take off they showed a seat for me that is far away from these people. I'm so grateful for this!!! I hate that I cannot figure out these things in advance. I WOULD BE HAPPY TO PAY MORE IN ADVANCE TO MAKE SURE THERE ARE NO FAMILIES W KIDS AROUND ME!!!!

Brand new aircraft Airbus 321neo, good seats although no recline (so no arguments with other passengers). Orderly boarding using front and rear aircraft doors for efficiency. Departed on time and artived 25min early. During check in, ground staff are very strict about permitted baggage and carry-on weight and size - you're only allowed what you paid for. Onboard food and beverage prices are a bit high but similar to airport coffee shops.

Boarding was fine, crew professional but not very friendly. Seats are very tight & uncomfortable. 1h delay due to crew change and mechanical issues - no communication whats going on.
