While I agree that QR is a significantly better airline than BA, please remember that grass is not ALWAYS greener - new DOH airport was delayed for a few years (I am not sue if it is QR fault though, but wait in Qatar everything is sort of owned by the Ruler, right?), the lounge situation just after opening was one big disaster and I am not even sure I like Al Mourjan (much prefer TK IST lounge that IMHO is world's best).
