Flew with Qatar when we (wife and kids) came back to the UK on a holiday back in April.
NEVER AGAIN.
A380 Sydney - Doha
B787 Doha - London
So 'modern' planes.
Ditto on the reverse flights.
ALL 4 flights had problems with the seat reclining mechanism (not just us but various passengers).
Doha airport is mentally expensive!
On the way out the Doha - London flight left from a different gate than the one the passengers were told to go to.
So...
They had a shuttle bus.
Or at least for the first group they did, then it disappeared.
When they finally got more, they crammed all us cattle class onto a couple, and the 20 or so 1st Class got one to themselves.
On the way back on the 787 the IFE didn't work.
They also bumped my eldest away from the family to allow a husband/wife to sit together.
We had reserved a seat for him on the outside as he is 6ft+ tall, he was bumped into a center seat, 5 rows back.
Tried to explain to the flight attendent, may as well have spoke to a wall, they weren't interested.
Service is SLOWWWWWW.
They always do the seats in the same order, so if you have a seat in the wrong place you never get a selection, just whats left.
Thoroughly horrible experience, have no intention of EVER repeating it.
Oh by the way, don't bother wasting your time complaining to the head office.
Recommend Emirates and Cathay Pacific.
Avoid - Qatar, Jetstar, and even Qantas (expensive for what you get)
