Bulgaria Air should stop using buses for boarding if possible. It is very inconvenient and delays the departure

Easy check in. Hot snack with wine if desired. Then chocolate, tea or coffee. Altogether excellent.

Seats are quite small, but due to the plane being empty we were aloud to switch seats to have more room

The water was handed out as we were entering the plane, instead of when we are set down and our hands are free of luggage. There was absolutely no food offered from Sofia to London, except a low quality chocolate, which was not delicious. The flight between London and Miami was ok, as far as service and food, but it was absolutely freezing, throughout the whole aircraft, especially in the back seats, I had to cover my head with a scarf, besides using the blanket and still I was feeling extremely uncomfortable. The passengers seating around me shared the same opinion. We did ask for something to be done about it. The gentleman did try to adjust it, but the effect last very short time, and towards the end of the flight it was extremely cold and blowing strong again ….

I’ve never heard of discover airlines but will definitely be on the lookout for future flights. Everything about the trip was perfect. The staff were exceedingly friendly and helpful. The only critique; there was a delay and gate change and this fact was NOT well published! My eTicket was NEVER updated with the new flight details. We ran the whole way from our connecting flight only to find that our flight was delayed. Very frustrating. Additionally, there was NO announcement regarding the root cause of the delay. The uncertainty about the cause of the delay contributes to the overall frustration. One other small matter onboard; one of the toilets was unavailable (or perhaps malfunctioning) and NO explanation was given nor was any workaround explained. It would have been less frustrating if they announced why the toilet was lock and explained the alternatives in detail. That way the foot traffic congestion could have been minimized.

Basically a low cost airline, with very small seats, mediocre food and staff not particularly nice. Not a pleasant flight

Plane was old and small. Crew was not very friendly and didn’t check in much or offer water more than 2 times over a 8 hour flight.

We were on a full-service fare as part of a long-haul trip so it was disappointing to be on such a no-frills flight (no meals/hot drinks/entertainment) especially for a 3.5hr flight, at the start of a long trip. The crew however we’re lovely & friendly.

Dislike standing for 30 minutes waiting to board. Coffee disgusting, hot sandwich almost inedible. Staff cheerful. Flight early.

Ryan air is a scamming airline. They advertise that you have to follow they baggage policy and their employees just do whatever they feel like. My most recent flight, i checked to large bags and just paid for 3 cabin bags and priority. Apparently, according to the staff, they knew the plane had too full in the cabin. This meant they had to target a select number of bags to into the hold. Now, a normal airline just offers to take your bag at the gate for you, it is their mistake. Not Ryan air, they just tell you the wheel of your bag sticks out 2 cm, we will charge you almost what you paid to check your entire luggage immediately, then tell you it’s on you. I would have gladly paid to check in the bags in the bag check in, where they told me the bag was good to go. Never using this airline again. I used to enjoy the quick direct flights but I will never use them again.

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

Waiting outside for a long time is not really necessary

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

The plane had only a few passengers, we got lucky. The crew was visibly inexperienced

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 🥶

Take off was great but landing is always with a bump.

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 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.

Everything was great…Flight Attendants were specially friendly and helpful.

Catastrophic experience the gate selected customers were picked up to.pay 70 eur for overweight 1-2 kg. While some others were let to board without chcking their carry on bags. Unecessaey drama by Lufthansa that brings nothing just hating them by customers.

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

Not great!!! Seats in Business class were horrible; no cushion!!!

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

It was good. The seats in economy weren’t bad

Everything was streamlined. Timely take off. Early landing. Great flight

Low-cost airline. Airbus A-320 and 321 series are not comfortable on flights taking more than 3 hours. Seats are uncomfortable. Very limited foot space, especially when having a bag under the seat in front of you.

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!!!!
