1) Phone to book the outbound F seats and the best return flight currently available. If something better comes up for the inbound I can change it for £35pp.
or
2) Book the 2 F seats now online and when inbound seats appear phone to add them to the 241 booking still incurring the £35pp fee.

As I understand it I can't avoid the change fee (assuming I change the inbound) but having seen the various warnings over taxes through the thread I just wanted to check with the experts on here that option 2 doesn't put me at risk of overpaying on taxes?

I'm not actually sure which my preferred option is but hoping someone can suggest how best to play it! Thanks in advance.
