We have a departing QR flight in February and would like to get an idea of the best lounge option. I have read that the AF lounge that QR has an agreement with is sub-optimal. Is there a consensus on whether it is worth the time to go to the Centurion lounge pre departure? Am I correct understanding that we would need to go through security twice? We are both pre and clear. Flight is at 3 PM, and we will be checking in approximately 2.5-3 hours in advance. Thank you!
