Sark - are the conditions as to the changeability and refundability of the 2 tickets you have in mind the same ? Are they both issued by the same airline, or is one done as a codeshare and issued by another airline and thus possibly governed by a different country's laws ? Are they for exactly the same outbound flight ? Are they for the exact same quality of seat ? Does one accrue more frequent flyer miles ? Do they have the same luggage allowance ?
And finally... does one of the tickets have "go faster" stripes ?
