I asked when I got to Al Mourjan in DOH if I was able to purchase access to Al Sawfa and they said yes for AED 350.00 (USD 95.00). I immediately left for the Al Sawfa lounge and the host at the escalator asked for boarding pass and I said I would like to pay, she let me up. When I got to desk they asked for ticket and then said it would be AED 250.00 (even better). I had a 6 hour layover and it was great. I was able to try the fantastic Krug Clos Du Mesnil 2003 which was the best champagne I have ever had. They also had Krug and La Grande Dame. Had a great meal and time in the lounge. I found out from the Duty Manager that they started offering this to passengers that were on a full fare business ticket (no upgraded ticket).
