Be aware though that BBMF's season runs May to Sept only (although the chippies and Dak do fly in the winter). They do not have any twin seat Spitfires but even if they did, the chances of getting a flight in one would be about zero.
The Boultbee Flight Academy currently based at Kidlington have a twin seat Spitfire - but before you get too excited, have a look at their website for prices...
Forgive me for also for saying so, but wouldn't a flypast from the Lanc be more fitting for Bomber Command
