Upgrade to Downgrade to Upgrade
Reminds me a recent BCN-LHR flight where I was upgraded at the gate to CE, downgraded after sitting in 1F just before door closed, then upgraded by Pursor/CSM back to CE, after door closed, to exit row 11A (yes CE went back to row 12).
Was a bit confused as a Oneworld Emerald and a BA nobody!
The new mugs are nice though...(It was freebie ticket which was maybe confusing not just me!!).
I prefer AA where you are likely to be upgraded, space available or by using the SWUs each year...why have empty cabins?
