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.

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.

Low cost carrier, you get what you pay for. Cardboard-quality seat, no recline, minimum pitch, bus-to-board service (no jetbridge), and overworked/underpaid flight attendants. But, they got the job done on-time with no major catastrophes.

The behavior of the front desk and lack of explanation of hidden fees and prices in emails send pre-flight marred things up. 1 star

2 hours delay, very disappointing, at least they didn’t cancel at all as they do often

I miss my flight due to boarding pass won’t load up

Flight schedule was modified and the final departure time delayed.

Big delay because of the weather but communication not so good. Boarding already late (due to tight schedule on Wizz side). When you get in you are hurried every second even if you still need a few seconds to arrange your bags. Food far away from how it looks in the catalogue and right on row 8 already out of chocolate although you are supposed to receive one for a menu. No replacement was offered.

The border control opens at 4:30 so there is no point in going in early as the wizz email suggests. Our flight utilized a plane with plastic seating which was really uncomfortable.

Check in took very long. All three priority agents left for lunch or something and the line did not move.

I enjoyed the comfort of Premium Economy. The Purser on London-Nairobi was a little testy, snappish in his tone. I understand stressed, tired, etc but his tone in addressing passengers I found wanting.

Outdated from start to finish. Good was inedible, choice was very poor. They don’t seem to care

Very good crew. The seating in economy plus was excellent, and I slept most of the way. The diabetic meal that I requested was almost tasteless--about a 2 on a ten-point scale.--so I ate little. And why bother serving dinner to fliers at midnight?! I had eaten a meal at the airport six hours earlier. A good breakfast would be better.

British Airways Flight 525 from Florence to London on July 29th 2025 was the worse flight I have ever been on. The flight was excessively delayed with poor communication from airline as to the reason for delay. We were notified of need for an unscheduled stop in Pisa after boarding due to weather which was limiting ability to fuel up to the capacity needed for the flight to London. Though we understand and appreciate the safety concern, on quick web search we later learned this was a recurrent problem. We were subsequently kicked off our connecting flight out of London to Port land, Oregon (also on British Airways) though that flight was also delayed (we were told we would not be able to make it in time, but ironically the amount of time it took for them to rebook us would have been more than sufficient to make the connection). We then had to stay overnight in London at a very mediocre hotel, had to take a flight out on a different carrier which involved a stop at LAX (not a direct flight to our home city which we had paid extra for the convenience). Half of our bags did not arrive in LA and we had to transfer the bags ourselves from the international terminal to terminal 6, only to have most of this luggage that made it from London to LAX not arrive in Portland. They bags were eventually found but took over 60 hours for delivery. The entire trip home which was suppose to be 13 hours took over 40.

Smooth roundtrip to Manchester, UK from SFO. I think BA is fabulous.

Flight was delayed. Though I checked in with BA live chat three times, our special meals were not provided.

My experience with British Airways is excellent, thanks for all 🫶🏻✈️

Our luggage arrived 2 days late when we reached Santorini. We were without cloths and toiletries for two days and didn't had time or means to go and shop everything at reasonable cost. Even though, we filed the report immediately at the airport, there was very less communication to us about when we would expected our luggage and even when it arrived there, they didn't had staff to deliver luggage to our hotel, so we had to go to airport to pick it up, which is very difficult and annoying to do in foreign country where you don't have you own vehicle and you don't have time because your tour is packed with activities. They could have tried to expedite the process and kept us informed and deliver the luggage at our hotel. Also, should have given us compensation for it.

Fair, difficult to find the departure gate. Luggage delayed on arrival

Very old aircraft. Seat 15 A & B personal light not working, foot rest broken in 15 A , reclining push buttons required two people to do it. Overall experience was below standard. The same food was served both the times. No snacks in the ally, drink choices very limited. It felt like it was the year 2000. The crew unfriendly, hospitality 4/10.
