Fact = BA on their monopoly of the GLA-LHR route are refusing to transfer bags at LHR to/from non- 'One World Alliance' partners.
This issue now rests with local MP (for possible MSP involvement) James Sheridan MP (aka Jim) at:
Jim Sheridan - Labour Member of Parliament for Paisley and Renfrewshire North
Luckily have the evidence of a reply from BA claiming NO GO on baggage transfers at LHR for anyone from GLA onto non 'One World' alliance partners.
Any other experiencing this travesty, please contact BA direct and Jim Sheridan MP, as above.
Thank you
