Which T5 Covid test for USA?
We're flying on 28th to ORD but staying previous night in Sofitel. AFAICS we can get an Express Test lateral flow done by Zone H or a Halo test in the Sofitel, which is obviously easier. The Halo website shows a US flag only on the
NAAT / LAMP TEST but has a lateral flow test available at only £15. Is that valid for BA?
