It's not difficult is it?
Regardless what it says in the FAQs, in the flight booking terms and conditions it states very clearly
''Passengers who purchase baggage will receive 22kg standard baggage allowance.This applies to new bookings only and is valid for bookings made until 31st January 2011''.
What I was trying to say is that it could be a bit of
PR spin to increase bookings with baggage in January. (usually summer holidays)
They may then announce it will be their standard baggage allowance for all future bookings. I guess we will have to wait and see, only 3 days left untill the end of the offer anyway. If this does however become the standard allowance then it will be a good thing as they are the most expensive airline to check-in bags with, even compared to Ryanair!
