I thought TUIFly were shutting down their Bremen base - if so that casts a doubt on the rest of the information. FMO-LTN seems a very odd route for TUFly to do considering that FMO is just a regional base for them and they would face competition from AB's STN service
EDIT - been on TUIFly website and at least some of the information is true, GLA-Stuttgart, CGN-LIS are bookable. GLA-BRE is bookable from Glasgow but not Bremen. No mention of Bremen-Stuttgart or LTN-FMO though, only London route bookable is Venice from Gatwick (probably a TOM charter)
