Whilst a couple of Virgin 747-100/200's have been to Luton over the years no aircraft from their current fleet (747-400/A340) have ever visited.
For the record, the runway problems at Gatwick last week resulted in four diversions from Gatwick - 1 x TOM 767 and 3 x EZY A319's. No Virgin aircraft.
Only one 747-400 has ever visited Luton - a BA example
Only one A340 has ever visited Luton - a Brunei Government aircraft.
