British Airways and Bulgaria Air fly direct to Sofia from Heathrow. BA is better as hand baggage allowance is 23 kg. The downside is they give you no refreshments. Just a tiny bottle of water and a ridiculously small piece of snack with maybe 5 bites of nothing! They do however sell food onboard which is pretty overpriced and tastes lame so better to buy food before you board.

Enough seat availability for us to move a little and so sit together - but the flight was half an hour late

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

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.

Waiting outside for a long time is not really necessary

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

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

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

Whole way through - far more professional and slick than I expected

You need to make signage at Berlin Airport clearer. Having checked in online we had our boarding passes onlour phones. You do not make it clear that you need to check in again to receive a printed luggage tag. You get to baggage drop off and it says you can only do it with a luggage tag BUT not how to get this.

We were bumped despite seats existing on flight While checkin attendants were helpful Easyjet management was not. Only after threats were we allowed on plane at last minute. The online help desk was useless and waste of time (over an hour of useless chats)

It was good except they could offer free water and tea/coffe

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

Sat at rear of aircraft and was very cold. As a frequent flyer for many years, this is was the coldest I have ever been. Other passengers and some crew were complaining how cold it was. Sitting near the doors always risks being colder, just the way the aircraft works - but this was exceptional, bring a good jumper. Everything else was pretty standard easyJet - good value low cost carrier.

The best budget airline in Europe. Flight was on time, crew friendly and worked hard during flight and were able to meet our needs. Only downside (not the airline's fault), there were no rear steps.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

Boarding and disembarking were smooth. Not offering free water was cheap ... I've never encountered that before on a flight.

Boarding could be better. To get through your gate but to be stood in a corridor for 20 minutes is not great.

Payd for long seats for our parents and because they don’t speak English fluent they have moved them. Absolutely scam!

The chairs don't recline and the food for sale didn't looks as appetising as its prices would suggest. But that's a low coster for you. Orher than that, the flight was delightfully uneventful.

The flight never took off because two naughty kids, Donnie and Bibi, did a silly thing. Started a war.

Even when you get the priority pass the experience is not what it meant to be priority

I wasn't able to check in before because I had no internet on a long ride over and I had to pay Euro 50 all together I paid an extra Euro 200 on top of the original flight because I had suitcase and carry on and I wasn't able to check in online before And the end it ends up being more expensive flight than a regular carrier You don't save money and the plane is less comfortable

Surprisingly, a very good flight. No wonder that Wizz flights are always full.

Boarding from Teminal C, which requires long walking to it from main terminal A.

delayed flight, bag was delivered earlier than I landed, no even water was offered during the flight...

The 50 € boarding fees per ticket are completely unjustified. I lost all my savings because I arrived at the counter barely 5 minutes late (2hrs and 55mine before departure). This feels like an unnecessary penalty. It's especially disappointing considering the initial flight was canceled by WizzAir. I expect a partial refund of the 196 € paid for the boarding.

Boarding kept us waiting for ~15 minutes in the sleeve. Other than that, excellent for a low cost carrier.

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

The crew and flight was fine and enjoyable…unfortunately, when I arrived to Bari and received my checked luggage(that I bought for this first trip to Europe), one of bags had a huge dent in it and the other had a completely damaged/broken wheel that made it very difficult to travel the rest of my time in Italy. Very disappointing and frustrating!

The plane was a long way from departure lounge. The plane looked tired but got us there.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Far easier than I expected it to be. Checked in online & had our boarding passes emailed through. Straight through security & boarded on time. No issues.

Shocking. Faults with the plane in both directions which caused delays with no compensation

Very efficient boarding. Plane lready for take ooff10 minutes before time.

Great crew. Seats do not recline :( but it is budget so i should have known. Otherwise comfy leather chair. Slight slim chair but again budget so expected. No entertainment do makes journey boring. Recommend packing plenty of snacks and games or download plenty of films and music in your device. Staff excellent. Clean flight. On time.

Both of my flights had issues with their time slot with air traffic control, so they left over an hour late and the flight back to London was delayed by over an hour. Please provide more clarity about baggage requirements on booking sites, your website and within the app. I had to pay for extra bags at the airport when departing London, because they didn’t specify that your carry on bag can only be a backpack and not a trolley, my trolley bag fit the size requirements of the backpack but still I was made to pay

The crew at Check-in was very helpful. It’s was appreciate.

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
