I am very confused by my 25K cert. I booked a refundable itinerary for 22,500 points (on porter). I now need to change it to a week earlier. I tried to change it and it said I can't do it online (the flights I want are available at the same price). So first question is, can it be changed if I call?
When I found I could not change it, I looked at cancelling and rebooking, however, it appears that because I only used it for 22.500 points instead of the full 25,000 that the discount will be forfeited entirely?
