I got up in this. No Elizabeth Line from Liverpool Street to LHR T3 (at around 0900) and the HEX was running a reduced service (the 0940 cancelled). Consequently, I missed my flight 1055 to OSL.

I got to security at around 1030, give or take a minute either side. When security scanned my boarding pass, the screen lit up like a Christmas tree. Back down to the desk only to be told that the next flight out to OSL was overbooked. Credit to the chap for trying to get me on both flights.

In the end, I opted for a reroute through HEL with the 0730 HEL to OSL. As this is an OSL journey start, I really didn't have a choice.
