Change of plans

Serves me right for being excited about my upcoming vacation.
I got a call from my flight operator and apparently the airline decided to cancel my return flight! My choices: come home a day earlier ('cause sure three and a half days would be enough time) or two days later (more vacation days would be required) or full refund. I spent the next hour at work checking other airlines (pay $700 to go somewhere that was supposed to cost me $530 - not likely) and then found a flight departing two days earlier and returning one day earlier - the times suck (who am I gonna get to pick me up at Pearson at 2 a.m.?) and it cost a bit more - but it would have to do. I called my little brother in Van and he ok'd the changes. All is now set (well, I still have to fax said operator my cancellation in writing to get the refund) and it better not need to be changed again! Grrr.
