I can guest someone on the following dates:

12-JAN-2013 / 14h00 / BRU / SN_RJ100
12-JAN-2013 / 18h00 / LGW GF / SN_RJ100...never went there...not the best I heard...but cannot be terrible
16-JAN-2013 / 07h30 / LHR T5 GF South / SN_RJ100...landing at 05h20 in LGW...depending on transfer time, only carry-on, so if on time 2 hours should be enough to enjoy breakfast with bubbles before heading to BRU...hopefully

...could guest also but not sure guesting is allowed

14-JAN-2013 / 19h30 / MRU / SN_RJ100
