Ok to clarify the confusing title
I want to book a club flight from edi to any of the Florida airports. I reserve my outbound at 355 as a single.
Then 4 weeks later (yes a long holiday) I try and reserve the inbound. However it seems that 2 singles are £120 more expensive than a return.
Can I then phone up and pay the £25 offline fee to add the return, thus saving £95 over buying a separate single to the return?
