Good evening, V-Flyers. First post here, so please be gentle with me 
I posted this on FT a week ago - 111 views and zero replies, so I'll ask the real experts here: (timeline changed for obvious reasons)
*snip*
Going on vacation next week.
Due to award unavailability in UC from IAH-BOS-LHR-(gateway)-IAH, I ended up booking BOS-LHR-IAD as a CO codeshare, with a separate paid itinerary (IAH-BOS-IAD-IAH) to get to and from the gateways.
(At the time the only way to use Washington as a gateway on an award itinerary was to fly IAH-DCA-IAD-LHR-IAD-DCA-IAH, with connect times between the DC airports a tad too close for comfort, plus the return flight is on a US national holiday.)
I am aware that paid and award PNRs cannot be combined.
When I check in at IAH, hopefully I can get the bags checked all the way through to LHR. What I'm seeing, however, on VS's website is the following:
Passengers who have booked connecting flights that appear on the same ticket can usually be through checked with their baggage to their final destination.
At some airports however you are required to collect your baggage and clear customs - even though your baggage may be tagged for to your final destination. See below for details.
Passengers who have arranged connecting flights using two or more different reservations and hold separate tickets for these flights must collect their baggage at the destination of their Virgin Atlantic flight, clear immigration and customs and re check in with the onward carrier.
I'm only seeing this on the VS's UK website - nothing like this appears on the US version.
Has anybody else had to re-check luggage (as opposed to the post-customs baggage belt) landside in a similar situation, or has VS checked the bags all the way through?

Thank you all in advance.
