You do not usually pay more when they change the flights
They changed ours twice on the outbound I was flying from London On to YUL nonstop then connecting in YYZ
2nd change I cancelled & booked with Porter YYZ to YUL
They changed the inbound from MIA to something that would take too long to get us home same day
I changed to FLL on Rouge
a few weeks later they changed that as well cancelled
so now we are doing MIA to YYZ
will just have to drive to Pearson & park there instead of the closer airport
fingers crossed no more changes
It is just crazy
