Hey FT

A company has decided to fly me over to their headquartered city for a fun-filled full day of in-site interviews. They are willing to pay for my flight.

Is collecting frequent flyer points ethical? I know lots of you guys fly on your employer's dime and collect FFPs, but given that I'm not hired yet, is this ethical?

Plus, what is the most tactful way of ... suggesting that the recruiter book me a ticket on a specific airline / alliance. How can I also ensure that my FFP status is reflected on the boarding pass?

Thanks :-:
