With the strikes going on due to what crew at BA claim is poverty pay, Qatar have sent BA some A320 aircraft to ease the effect on operations, this is because they have a 20% stake in the company and they want BA as an investor to do well and maintain profitability.
Here is a video of the Qatar flight replacing a BA one and their crew. The plane is an ex Al Maha meaning it still has that interior but it is still far better then what BA offers, if it had the Qatar cabin then there would be IFE on every seat, it goes to show that BA can’t even compete with a Low cost airline like the would be Al Maha which is now scrapped. The crew were all Qatar employees apart from the captain, and all the onboard catering and cutlery/utensils were all BA. This flight also used the British airways Fligth number and callsign.
Hope you enjoy
