Is this BOGOF offer valid for both EWR and DXB? Will be very useful if I can use it for DXB. Flew Y7 last week and they are not bad. LTN experience very pleasant although the DXB arrival lets them down a bit as they take your passports from you to get entry stamp whilst you are enjoying breakfast in the lounge but it takes them so long to return passport to you and then there are never any taxis at the executive terminal so you wait 30+ minutes. Works out quite a bit slower than arriving at Terminal 1.
