This is one of those unanswerable posts and I'm really writing it for any suggestions rather than expecting people to be able to answer a "how valuable is..." which is so subjective. Anyhow hopefully you will tolerate it. Basically three long trips have gone from being "client organised" to "self organised" and by putting them onto QR via Doha I will not only spend less money but get enough tier points to be GGL by year end... only snag is the timings of the QR flights are much less convenient than the BA directs (I will lose about a day each trip) I sleep well on long overnights to and from the Far East and generally everything will be a bit more hassle with co-ordinating things. So for those who are GGL.. worth the hassle?
