Did I read somewhere that BA Holidays booking are less likely to be upgraded or is that a myth? I have a LHR JFK MCO LGW routing coming up in J / F / W booked as a BA Holidays booking with car and just wondered if I should look into UuA or settle with what I have and hope the W OpUps to a J, as I'm happy either way.

I usually book BA Holidays where possible for the payment flexibility but didn't consider what that does to my OpUp chances, if indeed anything.
