We had WestJet tickets. The refund was quick when they cancelled. We booked quickly thereafter on Delta. We are on the west coast so we have a bit of a milk run (but almost always do). I think we booked at the right time, though, because we went from regular seats to Delta Comfort seats for $500 less per person that our original WestJet tickets. I have looked and it seems prices have gone up significantly on Delta since we booked.
