I ignored offer of u/g ET-CE for €125 at MAD check-in desk on 16/4 as I was already booked in CE; but would have regretted it if I'd been booked in ET as they flew in a longhaul 763 and my 2F in CE became 1K in CW. Of course, there was no IFE and dinner was the usual choice between curry A and curry B - but let's not be churlish!
