Multi city with avios companion voucher

[NYC]

Hi all, Can anyone advise if you can book a multi city avios companion voucher ticket on line. I’m looking to book London to Vancouver and Seattle to London but I can’t see how to do it on the website. Or is it you have to phone to call centre.

Thanks all

That’s an open-jaw booking. You have to either call BA to book it, or book both legs separately online and request 50% of the avios back for the return sector. There are numerous threads and articles on here with information about doing this.

That’s great thanks for that.
Much appreciated
