Hi!
Is there an advance period prior departure before those cash upgrades are offered?
I have a flight in more than 100 days (unusual for me) - and the outbound could not be booked in D1/ FC - connecting through JFK from SFO - inbound somehow worked.
So I was planning on cash upgrade. But despite the D1 cabin is totally empty (upgrade list shows 36 available seats) - no cash offer is available. Neither for the connecting flight in the FC cabin.
And as a Platinum - also the comfort plus seats can not be selected nor were available at ticketing
