Hello:
Please note, effective March 1 2009 the Elite allowance will be reduced to 3 pieces. Same increased weight limits.
Not sure, but is there a code share flight on your return trip. I.e. and AC flight number on someone else's equipment? If yes, would your AC allowance of 4, soon to be 3 be OK without an additional payment? Just a thought for something to look into.
Cheers
