I get a constant stream of emails asking for advice on booking British Airways redemption flights using the British Airways American Express 2-4-1 voucher.
If you want to be 100% certain of getting the flights you want, you have to follow a very strict routine:
You need to book your outbound flight 355 days before you want to travel, which is the time that tickets become available for sale and BA releases the guaranteed two Business Class and four Economy Class seats
You need to call at midnight (1am during British Summer Time) because the flights do not drop into the online system until later
Book the outbound flights you want as a one-way booking
When your return flights become available at 355 days before departure, you need to repeat the process – and usually paying a £35 per person change fee (EDIT: comments below suggest that BA is now waiving this) – to get the return added on to your outbound
The snag here is that the UK BA call centres are not open at midnight ….
Which British Airways offices are open now?
A few years ago, Flyertalk member dunk created a website which lets you bring up a list of which BA call centres are open at any particular time.
You can access the tool here. It will show you which of the UK, German, Japanese, Hong Kong or Indian BAEC service centres are currently open, as well as other general BA numbers.
I can’t vouch for the accuracy of this tool but I’ve never seen any complaints about it. There is one bug – I couldn’t get the ‘give me a number which is open when my local time is XX:XX’ button to work, so you are reliant on looking at the site at the time you need to call and using one of the ‘currently open’ numbers.
