OMW is to cover incidents beyond airline control (war, acts of god, weather etc....) airlines are supposed to cover operational stuff... mechanical breakdown and staffing issues are considered airline issue so they should cover u!

u have a better chance of compensation by talking / complaining to the US FAA, because they have a better passenger bill of rights in the US as compared to Canada.......

i understand for more than 3-4 hrs u should get a food coupon

my advice.... sit in lounge, eat more, drink more, surf more web..... and chat up with UA staff and see if they could help u..... cause they helped me re-schd my AC exSFO flight following a snow storm in its departure.... and accomodated me until 2am at their RCC lounge...

if urs a UA (AC metal) codeshare tix, you should have asked UA to accomodate u.... like via LAX, SFO, YYC, PDX, SEA, YEG or something then connect to YVR

good grief....some pax have to calm themselves down..... i dont understand.... sometimes why pple are sooo frustrated for something soo minor distruption in life.....
