The airline is gaming low cost market with low prices sold to 3rd parties, odd cabin arrangement and overall subpar customer experience.
We did 4 legs of flight with them, and we will not use their service again.
First - the price. We bought the fare at low cost via 3rd party buying tickets in bulk at a discount. Changes on those 3rd party bookings, though, were charged double - once per agent, then the airline, plus other fees, of course. Change to one leg costed almost the same as a whole one-way ticket. I think that's how they make profit - price dumping on a price of a fare in search engine then recouping losses on changes.
Second - check-in. There was no online check-in. Seats were allocated on first come, first serve basis at the desk with no consideration for families seating together. We were a family of 4 and everyone was assigned a seat in a different row. We had to trade with passengers. We arrived 3 hours before departure. Queue was 1.5hrs.
Third - cabin arrangement. On 777 they give good leg room (it's one of the selection criteria on many searches) but made seats narrow - their layout has one more column of seats compared to competition. I was more comfortable on other airlines' seats.
Fourth - food. It was good; way better than what other alines offer.
Fifth - language. Only selected staff on the airplane and their hub airport spoke english beyond the basics.

it was the cheapest available flight and the time's were good.
im not sure if its the legroom or the seat quality but i found it quite uncomfortable compared to other airlines. food quality wasn't great and they were a bit stingy. no alcohol apart grom a few cans of beer which quickly disappeared.
on the second leg there were two problems with passengers that were dealt with very professionally by the staff, in fact they were great throughout. also it was the first time that I have not been offered a headset. tbf the stewardess sorted some cellphone type ear plugs on request which were fine.
so not too comfortable, poor entertainment, no alcohol and average food at best. however the plane seemed pretty new and if you can put up with a little discomfort to save a few hundred pounds then its fine. i would use again if the price was right

My girlfriend has a invincible handicap, she was refused any kind of assistance and we had a terrible boarding and flight.

Without a doubt, the worst company I have ever seen in my life, the staff is unpleasant and with no willingness to help you, the worst experience I have had in my life, I don't know how they can continue working with the terrible service they offer, in My case was with an airline official at the Bangkok airport. If they are not willing to serve their customers, customers who have paid a lot of money for their tickets, let them go do something else. The company moves at the pace of the type of client it has. My opinion for them is 0. I will never fly with this company again, before flying with them again, I will walk anywhere.

This is an horrible airlines company with a bad Customer Service (never answered to my calls and emails). I travelled from London Heathrow and Bangkok and my luggage never arrived at the final destination, because was damaged at the Heathrow Airport. The result of this luggage damaged was that a lot of personal items were damaged and missing/lost. I made my claim but the company disappeared and couldn't be reached by phone/mail and by CAA. I am bringing them to the court. Avoid this company since I never had a problem like that.
