LHR-TXL-LHR
Was checking in for tomorrow's flight on the iPhone app.
BA982 (LHR-TXL): On the first screen it said upgrade offers available but when I went in, it said the special offer was sold out & quoted me £550 for an upgrade to CE. Curiously, the seat plan shows ET starting at row 5. I thought 4 rows of CE was a bit on the lower side.
BA 987 (TXL-LHR): On the same page, this was available for £69 which I believe is the standard for this zone. This flight is on 14/2/13.
If you are curious, I haven't opted for either. Saving up for some long hall POUG offers or a flight that is longer than than an hour and a half.
