Cash+miles redemption on a UA flight

Hi

Am I able to mix classes on this, i.e. I have 50k BMI miles which I'd like to use doing LHR-SFO in UA F out and J back?
Wasn't sure from the BMI website if you can mix reward classes.

Thanks

Mixing reward classes isnt a problem. It is always recommended to book two single trips rather than a return anyway - it lets you change the return leg if you need to then. Otherwise the return cant be changed once you have started the outbound leg.

Remember F charges are 2.5*miles and 2.5*cash now.

Thanks greyt (fellow greyhound owner?)

So have I got my (miles) sums OK -

LHR-SFO in First using miles+cash = 12,500 miles * 2.5 = 31250 miles + 75 * 2.5 = 175

SFO-LHR in J using miles+cash = 12,500 miles * 1.5 = 18750 miles + 75 * 1.5 = 112.50

Total = 50,000 miles and 287.50 + taxes, APD etc.

Cheers
Andy

Looks right to me Andy and I agree with greyt, book as two single trips.

Many thanks DW
