We had to cancel a flight that we had booked through Gurufare. Gurufare said that for an extra $300 the cost of that cancelled flight could be applied as a credit for a flight in the next six months to anywhere that airline flies. We paid the $300 only to learn when we tried to use it that the credit was available only for a flight with the same origin/destination. Gurufare's reply says that they sent two emails confirming their policy, one before and one after the charge. Our memory is that the charge was made after a phone call where the representative did not mention the limitation. We have reviewed our emails from Gurufare around this time and only see one email from them, the one sent after the charge. We are not asking for a refund of the cost of the flight we cancelled, just a refund of the $300 paid to secure a credit that turned out not to be usable in the way it was described.
