It is T60, so for you the end of May.
The way you choose your seat is changing
We know how important choosing a seat is to you and over the last couple of years we’ve been working hard and investing in ways to improve the process.
If you are in Upper Class, Premium Economy, Economy booked in Y or B class, a Flying Club Gold member or you made a confirmed booking on or before 16 December 2013, you will be exempt from any charges for selecting your seat.
From 25 June, all Economy customers will be able to select seats free of charge at check in but for those customers wanting to assign a seat before this time, the service will be available for a fee.
This means that until 25 June, all customers will be able to select their seats free of charge from 60 days before flight departure.
From 25 June, seats will be available to select from time of booking up to 336 days before departure.
Charges will apply to all routes (except London Heathrow to Tokyo).
When you can assign your seats
The process to select your seat is changing and will launch on 25 June 2014.
