Mmm - strange. I've just rebooted and still the same. The same (blank screen) appears if I try to access Meal Request, Upgrade Your Booking, Chauffeur Drive Request etc.
The Flight Details below is also laid out strangely with all 4 flights listed twice and all as "Onward" flights where I think they usually show as Outbound, Onward and Return.
Is this latter bit the same for anybody else?
