I am taking a trip to London. I have one flight that I can book that would basically be able to apply the miles to either AA, Delta and Virgin.

I am on All 3 programs with one flight on Delta this year; 15K points on AA from last year and 2k on Virgin. No status on any of them and looking to start the year fresh. I will be doing at least quarterly trips to from NYC - LA. They all seem to have comparable flights for that segment.

Since this London trip would be a huge start to one of these programs, which one should I book it on?

Appreciate all the help.

Thanks,
Bo
