Hi FTalkers!

I am about to give a call and attempt to book for next Feb, Off-Peak LHR-HND and use my GUF2 and my AMEX 241. Let me know please if the steps are correct
Ring YouFirst
Ask them to use GUF2 on A revenue for the dates i want out/inbound and use avios. Once i get the quote, ask to apply also the 241 voucher
As per https://myflightpath.club/redemption-calculator calculator, this should cost 150000 avios + taxes and fees (approximately £850-900 pp)
Am i right? Anything else or specific to mention if the agent start saying that there has to be award availability? Do i need (I) availability (there's none) or can go straight to (A) ?

Thanks!
