Ok, so booked last November for travel in July ... I trust the timelines will move along.
However, I do most emphatically NOT want a voucher. I will, eventually, want a Refund for 2 TATL tickets in First.
If BA can get us JER-UK by then, and if LHR-IAD (BA217) is still operating, the ‘Book With Confidence’ doesn’t give me confidence we will get a FULL cash refund on that PNR ... on the basis that the USA won’t let us in anyway!

Minority interest ... I’ll see what evolves.
