I think that there is a structural quid pro quo that the airlines/hotels/3rd party travel sites might be on the threshold of considering.
Institute a 48 hour option to cancel for BOTH suppliers and customers.
For suppliers, 48 hours should be enough time to fix just about any 'mistake' or 'error' fare/rate with no liability.
For customers, 48 hours should be enough time to make an unpressured decision about committing to purchasing an itinerary.
While its a mildly amusing intellectual challenge to fight for these glitch fares (and I have only participated in one....and put up a 2 week pitched battele before prevailing!!), it would be a shame if FT became branded as just another bottom-feeding website like Fat Wallet.
Here's hoping that the travel industry gives itself and its customers a little more breathing room (ie- 48 hr. option to cancel policy) in the near future.
