Well tis isn't African travel but I'm not sure where else to make the post, and I know there are a lot of schemers here that might have the answer to this.

We're in the UK on an ex-pat deal and as part of the deal we have four first class tickets back to Canada to be used whenever we want to visit, the value of these flights is $25000.00. Well we've seen Canada and would rather use the tickets for a different trip but the company is only willing to pay for the agreed on tickets. Is it possible to purchase the flight to Canada then cancell and trade the tickets for a different destination?

Thanks

Only the airline you buy the ticket on can tell you the correct answer...and you may not like it.
Good luck.

Get in touch with the airline and see what your choices are.
