Hey Marc;
Hope you had good trip in Mexico - sorry to hear about the flights back and the tanks. Remember Air Canada's motto = "we are not happy unless you are not happy

.
Just got back last nite myself after another two weeks doewn in PDC. No problems with gear or two sets of tanks - maybe they are getting used to the bags by now!!
Let me know how your claim goes with A.C. - my last one after a big cf in Houston didnt work out too well.
Cheers
