Can't see this posted, and slightly better than usual as it now includes D and R classes.....albeit for a shorter booking window...

Dear Surturminn,

First is an experience that starts as soon as you've booked your flight. As a First traveller you enter a different world where personal service and attention to detail define your journey, from check-in through to your final destination — a world where every seat along the way is first class. And now's your chance to take that seat.

You can upgrade to First one-way when you book an eligible, semi-flexible, published Club World return flight in C, D or R class between 7 January and 29 January 2013 or a fully-flexible, published, Club World return flight in J class between 7 January and 22 March 2013.

You can travel anytime between 7 January and 22 March 2013, or up to 14 April 2013 for inbound flights.

Either way, you can book as many free upgrades as you like on eligible flights within the offer period. And they're all on us.

To book, simply call us on 0800 123 111 or contact your travel agent. When you book, you can ask for your free upgrade to First on the outbound or return part of your journey — whichever you prefer.

This offer is always popular so, bearing in mind upgrades are subject to availability, book early to avoid disappointment
