Didn't realise Air Canada had actually sourced an aircraft in C-GHPE and dedicated it to YYZ-DUB !
That aircraft has operated most flights this season. Only time I can remember a different aircraft was 15 July as C-GHPE was on ground in Dublin after cabin pressure problem on 14 July.
B777-200ER they used into DUB today, reg: C-FIUF
Think they meant that one as its the closest match to C-GHPE in terms of passengers.
