19 days, but flight plans have changed again lol. My flight from Toronto-Vegas was cancelled and I was changed to a Toronto-Calgary, Calgary-Vegas flight. Only problem -was that my trip starts in Ottawa, where they had me scheduled to leave Ottawa at 6:30am, arriving in Toronto 7:33.... and my Toronto-Calgary flight leaves at 6:45am. Got it sorted out with Delta though and I'm now going to Toronto the day before. Hopefully this is the last change, as the changes originally started in March when I was supposed to fly on the 15th!
