You're a mine of information ExXB thank you.
Am I reading what you say correctly when I state Article 3(b) offers me assistance on a through ticket with SQ who ticket me DUB-LHR on EI and LHR-SIN on SQ but I'm not covered on the way back? If EI don't run the LHR-DUB sector, SQ
are not compelled by this regulation to provide care, although they may do so as a matter of policy
so in this case EI don't have to worry about Article 3.
