Per https://www.flyertalk.com/forum/brit...after-use.html - I have no way of checking availability with this type of voucher. I believe it's "I" class, and there's no way to check online, only phone?

Please can someone check:

* BA85
* Friday 1st September (or a day or two before)
* Business class (Y or I) but using a "premium plus" companion voucher.

Thanks
