We have just flown with Qatar, here is my review
1. 1st flight from London Heathrow to Doha. 7 hours. Modern plane(seats 3,3,3 across), very comfortable, great entertainment system, food good, service good.
2. 2nd flight from Doha to Mahe, Seychelles. 5 hours. Older plane but fine, (seats 3,3 across). One of our entertainment screens not working on this flight, flight not full so my husband changed seats. Apart from that all good on this flight too. Slight problem at Seychelles airport as no wheelchair assistance (as requested) available for elderly parents but they just about managed to walk to taxis.
3. 3rd flight from Mahe, Seychelles. 5 hours. (Seats 3,3 across)Entertainment system didn't work for at least 5 out of our group of 30 travelling together. Flight was full, so couldn't change seats. Very disappointed that Flight Attendants woudn't offer any compensation for this, they said that "it's the aircraft and happens alot".
4. 4th flight from Doha to London Heathrow. 7 hours. Very old plane. Seat formation 2,4,2. Two sections of economy front and rear. Our entertainment system worked, but the couple next to us both of there's didn't (and apparently hadn't on their other flight too).
Seats uncomfortable. Control for entertainment system is fixed to side of armrest so difficult to use (no touch screen on this one) Entertainment screen very dark. Couldn't hear the film at times as engine noise was so loud. No USB connector.
Not enough toilets and they are all at the rear of the plane which caused problems when they were serving meals and people from the front of the economy section were trying to get to the back.
Qatar says it is a 5* airline. In our experience it certainly was not. If you get a modern plane it is ok, but the 5 hour flight with no entertainment system, followed by a 7 hour flight on a very old plane with none of the facilities that Qatar promises when you book the flight,means that we won't be booking with them again. We have experienced entertainment systems not working with other airlines and have given vouchers as a gesture of goodwill. Qatar obviously aren't interested in delivering what their customers have paid for, otherwise they wouldn't have such a huge problem with their entertainment systems - and would offer some sort of gesture to affected customers.
We will be flying to Australia next , and we will be flying with Singapore or Emirates, who we have flown with before and have had excellent service from.
