I want to book LHR-MEX and CUN-LGW as an open-jaw in J using a voucher. I've tried various ways to try to work out the taxes and fees but get a different number every time I do it!

I know I need to call to book it, but the cost of the fees etc. will determine if we look at other options or not.

Any help appreciated!
