For family reasons, I'm planning a trip from A to B. Airlines are currently not operating the route but flights are already available for the coming weeks, at less than normal prices. Airlines are offering a "safe booking commitment", with no charge for change of date in case of canceled flight (the only obvious and fair thing to do anyway). However, they will charge the price difference. For instance, British Airways states:
We’ve waived our change booking fee so you will not be charged, although you will need to pay any difference in fare.
Imagine this scenario. I book today a flight for the 25th of May. Say on the 20th of May I am told the flight is cancelled. The next available flight is the 1st of June, which was already available today (I just wanted to flight earlier). Naturally, there are less seats available on the 1st of June flight. Moreover, is closer to date. Based on how airline costs seats, that means the price should be higher. Therefore, although there would be no cost for the change itself, if I take the 1st of June flight I would need to pay much more. In other words, I lost. An alternative is to book a much later flight, say the 15th of June. By that time, prices might be closer to normal. I lose anyway. Perhaps the only way of getting the same price is for flights available on July. Too late.
My fear is based on a real possibility. Today, flights from A to B in May are four times higher than yesterday. Well, yesterday I almost bought one ticket for the 10th of May. You would say "what a shame you didn't buy it". But actually, if they cancel my flight, I would have to repay the difference! And all May tickets went up four times! So, it seems I was lucky not to buy the ticket! This is what has prompted this question.
Have you read or experienced this? I haven't found online articles discussing this risk.
