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

Usual issues with flight delay. Perennial problem of travel by plane.

i didnt go this was a hacker booked this flight on my debit card !

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Long delay resulted in my being unable to catch a train home and resulted in an additional £76 cost for an Uber

I was charged at the gate for bags I had already paid for. There was no other option. I am trying diligently thought easyJet website but making no progress HELP!

Changed flight terminals/gates twice. The staff and hospitality was good.

Boarding was efficient. Flight left on time. Wasn’t full so we could spread out a bit. Food was ok.

Used to be my "go to" airline but would be my last choice these days. I think some of the cabin crew believe it would be a great job if it wasn't for the customers.

I love travelling with British airways because everything is supper goog

Not that great. There were no entertainment screens, internet, or any way to track the flight path. The seats were fixed in order not to recline at all. The crew and the staff at the check-in counters were the only nice thing.

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

my flight was canceled and rescheduled for two days later

They oversold and down graded me from Premium economy to coach. 75-pound compensation is insufficient if you chose a particular class. I get dehydrated and severe Charley Horse cramps. I requested a bottle of water, even half even less… but no- “We are only allowed to give water by the glass. Nonsense. Lastly, their planes now have a fixed barrier between seats. So even if your entire row is empty, you are confined to just your space. Lastly, London now requires a transit visa for $30 for US citizens. Never travel through London again

I love British Airlines but I think it’s time for a change.My seat was occupied by very large passengers sitting next to me,I felt very uncomfortable and very bad.I’m sorry but I have to say it.

We had to pay extra for seats and bags (even for an international flight). I paid for extra comfort seats, but it was under an overhead bin that the crew used for supplies. I paid extra hoping to get sleep. We were constantly woken up by the crew opening and closing the bins. Our seat shouldn't be considered extra comfort. We paid significantly more than the rest of the cabin for these seats
