Did you mean that Birmingham isn't listed as a 787 destination?
Birmingham certainly does have a Thomson holidays 767-300 service to BGI from 23/12/13-13/4/14 ex BHX each Sunday.
Yes, as per reading the original question, he clearly states his friends have paid extra to be on the
Dreamliner, and BHX is not listed as a
Dreamliner destination yet.
Im fully aware BHX has B767 long haul flights.
