I can not book the itin in one, because the MAN-SIN.......... is already issued some month ago.
And no Flybe does not check through onto any other airline ! I already did this last year via DUS-BHX, and them told me in DUS them generally not check through.....
However i simply want to avoid to go landside in UK. BP's are not the problem! I can print out them during OLCI and bring for KL/Brusselair/LH or whoever check us through. KL ex AMS is the cheapest cost less than 70 Euro, Brussels aprox 95 and LH around 110 ( all i think + luggage )
