Has anyone done this? Or know how it works?
BA's website says you can upgrade an existing booking (I don't have one yet) or book and upgrade at the same time. I found a coach fare from SAN to EDI for $926 for next April. However, when I attempt to "book and upgrade" it says 25k miles plus $1700.
Is this the equivalent of only being able to upgrade certain coach fares?
Would I have better luck booking the cheap economy ticket and then trying the "upgrade an existing booking."
Thanks
