We are about to book a Round the World ticket for Sept 2010- March 2011. The travel company has been very helpful but say that any changes to dates once we've paid, we have to contact the airline ourselves and incur charges of £22-55 per change. The original travel company I contacted seemed to have a better arrangement whereby any changes incur a fee of £30 per person, even if changing a few dates at a time. Obviously one date change could have a knock-on effect on the others, depending on how tightly scheduled a particular part of the trip was.
My questiona are: how likely is it that we would have to make changes and if it is likely are we better to go with the company which charges the one-off fee?
