Hi all. I've been stuck with a 15 hour lay-over in Riyadh. I didn't realise what a terrible airport it is until after and now I have no option but to suck it up. My question regards the business class lounge - does anyone know if it's a pay-in lounge, i.e. whether I can pay a one-time fee to use it for the 17 hour period? And what that fee would be? I've done that in other airports where I've had long layovers and it's made life tolerable, so I thought it would be worth checking out.
