You probably couldn't have said it better but that's not the point.
Obviously, there will be passengers who will be allowed through immigration when they get to the US and will want the flight to go ahead.
AS a UK citizen, I will not be allowed in since Trump issued the updated travel advisory including UK and Ireland in the list of excluded nationals.
I'm booked onto a flight to MIA at 10:010 tomorrow (17th) which, being less than 24 hours away, is now open for check in.
I've tried checking in but get a message that says I will need to check in at the airport.
Since I live in Cheshire, this means that I will have to travel down tonight, pay for a hotel and take my luggage to the airport just to be told that I can't fly.
If I don't show, I will not be able to claim a refund.
If Virgin cancelled my ticket (not necessarily the flight), it would save me from the travel today and tomorrow, would allow me to cancel my 2 weeks accommodation and airport transfers with a glimmer of hope for getting some kind of refund.
I've spent 4 hours on the phone and tried SMS and twitter but all to no avail.
No doubt there are several hundred other people on tomorrow's flights in similar predicaments so I agree with the OP.
Something is not right here.
Virgin Atlantic should take clear action, their website should contain up to date information, that information should not be ambiguous ("we are currently evaluating what this means" is not very helpful). Other airlines are doing this in a much better way.
