Regular readers here at the Spaceship will know that I travel a lot on airlines, and that of all the airports that I have to go to, Aird of Sleat is the worst.
(From the Douglas Adams book the "Meaning of Liff" "AIRD OF SLEAT (n. archaic): Ancient Scottish curse placed from afar on the stretch of land now occupied by Heathrow Airport.")
Here is a lovely YouTube video of the kind of crap that you go through when travelling there.
Solution: if going to London on business go to the very nice and effective London City Airport. (Short haul only, sorry non-Europeans) or if changing, go to via Amsterdam, Copenhagen, or even Frankfurt. Munich is also good.
Problem: SAP UK headquarters is nearest Heathrow.
Also to overcome the "really, really, only one piece of hand baggage" crap I bought another Rimowa case, bringing my total to four now. This one holds PC and clean underpants in perfect harmony.
I mean seriously, if you're going to commit suicide on the plane, you don't need to pack stuff for your onward journey, so you are unlikely to decide, "damn, after I have my clothes for the after life, I have no room for the bomb in my one piece of hand baggage, better leave it."
