I booked an upcoming DUB-DOH-HKG with a 3rd party, Booking.com

It’s my 1st QR flight and I have to be honest, having heard all the hype about Qatar’s supposed level of service, I was totally unaware and unprepared for a Ryanair-esque nickel-and-dime Business Lite offering.

At no stage during the Booking.com process was there mention of “No Lounge access”, and indeed my current itinerary printout from Booking merely states that my class of travel is “Business”. When I check the QR app, however, my booking has the dreaded “P” after it. A word to the wise, Avoid the likes of Booking.com like the plague!


I’m currently BA Silver (OWSapp)
Having read the esteemed preceding posts, can I deduce that:
i) I have access to the Gold and Silver lounge in DOH?
ii) I can pay a fee to access the AM lounge?
iii) On return, I can access CX lounge in HKG?

Currently MMB only offers me The Oryx to purchase, hence my query about paying for AM.
Additionally, do I get access to the 3rd Party lounge (East Lounge) in Dub?
