We often talk about skin in the game and this is an area I feel I am qualified to discuss as a Gold Card Holder that has previously worked for Swissport (BA's handling agent in Las Vegas, though my experience is at various stations in the UK) and also happened to pass through LAS a few days before the day 2 PCR requirement was introduced.
I find it staggering that some (including an ex BA crew member!) are alleging the local Ground Staff are taking bribes to refuse passengers & pass them onto a local testing company, this is frankly an outrageous suggestion.
I do feel that there may be training issues that urgently need addressing but the suggestion that Ground Staff are involved in underhand practice is grossly unfair and inappropriate.
I'd suggest that some in this thread need to rethink their contributions.
