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 ….

Cons: "Staff seemed confused and would not let us seat at our assigned seats which we picked in order to accommodate our baby. Instead they put us in an even worse spot and decided to ignore the people that took out seats and left them be."
Cons: "Them actually refunding my flight when I couldn't legally travel due to COVID lockdowns."

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

This was our first time using them. I gave okay ratings for food and entertainment because it was minimal or not provided so I couldn't judge, but much better than most budget carriers we have ever used.

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

This was the worst boarding ever. We were kept in the boarding bus for almost 40 minutes without any information or update. Very uncomfortable beings squished with another 50 people and not knowing what was happening.

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

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.

I liked nothing. An extremely uncomfortable flight, staff were rude, no ice for my drink. 4 hours of misery

Good value for the money. Good leg room. Take off and landing very good.

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.

Crews are great, chill, good snack sets on offer, I didn't feel they play any annoying budget airline games. I will probably fly with Wizz every chance I get it

If you don't want to pay a lot at check in desk, you need to use online check in tool, but you still need to go to check in desk to have it printed out. Then what's the meaning of "online check in"? Extra security check, as if 9/11 just happened!

After adding baggage costs, and considering the necessity to re-checkin at each stop, and the €50 I was tricked out of for the ridiculous 3 hour min check in, I’ll never fly this very hungry Hungarian airline again!

This airline is routinely voted the worse airline in Europe for good reason. If you have an option, just avoid them.

Everything was great until it came time to pick up our luggage. We arrived in orly airport terminal 1, our luggage arrived in terminal 2. No signs to tell us, we waited for almost an hour before someone figured it out.

All in all is not bad, but the boarding by walking outside in the airport airplanes area in the wind and rain to go up the stairs to board the plane that’s too much inconvenient. Hopefully that will change and we use the normal gates at the airport to board the plane! Thank you!

I always have issues to connect with BA WIFI. Nothing to blame BA for but there is always an issue getting a gate at any London Airport whether the flight is on time or delayed. But overall a great flight.

Bad. After 3 hours on tarmac, flight got cancelled. No assistance whatsoever from BA.

We had airport assistance which was good except at Heraklion it was very difficult to find any staff to ask where to go which proved stressful

The wheelchair service was good. Staff and crew were helpful/supportive. The business of 'being overbooked' ....."you may not be able to travel tonight/we may have to put you in Economy'" was rather unsettling. Even Economy Plus in a MIDDLE seat felt cramped. The seating and experience felt very basic even though I had struggled to pay for extra - Economy Plus.

Flight was good but seat in 12D was not comfortable, better on the Airbus 321 from Tampa to Charlotte. No breakfast was served before landing in zLonfon only a coffee and orange juice.

I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.

Easy boarding, very friendly crew, short flight so no entertainment… needed cc for all food and drink purchases…. clean and on time … that is all that mattered… so overall very good.

The entertainment selection was ok, but overall not bad! The crew was great.

Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.

Checking in process could use streamlining when it comes to all info required.not bad tho
