The topic of airfare price drops has been done to death I guess but I'll give it another whack. Is Air Canada the worst offender?
I am not an experienced air traveller but I was very surprised to find the airfare for the same flights I booked in early February from Australia to Vancouver return (Sep/Oct travel) have dropped by 25% six weeks later! I booked the cheapest fare (economy tango) for my family on our first international trip and I chose Air Canada because it is a direct flight and we have limited time during school holidays. The airlines seem to know when it is holiday time and bump up the prices.
I have to say 25% is a significant price drop for the same class seats on the same flights. I am disappointed at losing $2000 and it is an unfortunate lesson. If I could afford the higher fares I gather the tickets would be refundable and I would not lose out, except for the nasty cancellation fee. My tickets are not refundable and I am informed there is no option to rebook at the new lower fare. I wouldn't mind so much if the price drop wasn't so large.
If this is a normal occurrence it seems booking with Air Canada is like spending money on a lottery ticket.
