Upgrade by paying GRU – IAH
Do you think its possible to get an upgrade on this flight if I have no miles, and would pay for this upgrade?
Just to clarify: you bought a ticket with cash (not miles) and you’re asking if you might be able to upgrade using cash? You’d have to look at the fare class to see if there’s even a chance it’s upgradeable. The cheapest economy fares are not.
