London calling

Have had a testing couple of days getting from stage 1 to stage 2 of our trip.
Exited Longyearbyen on SAS as planned - nice man at the check-in said he'd check our baggage through to Heathrow even tho' we were transferring to BA at Oslo (see later).
Pilot even did the right thing flying down the fjord at 1500 feet until we reached the coast.
Reached Tromso in northern Norway - had to go through a very confusing customs process as Svalbard is administered by Norway but is not strictly part of it and is tax-free.
On to Oslo where we managed to make a real hash of getting onto our BA flight to Heathrow - ended up OK but we went through immigration prematurely, had to get that cancelled, eventually got it sorted. Seemed our luggage could be transferred through but not our bodies!
Arrived at Heathrow to find that Sue's case had survived the process but not Jack's - identical cases with identical labelling!
Consistent with our track record so far, we find London in the midst of rioting, looting and other mayhem. Thankfully some distance from Heathrow.
Have lost a day camped in London but have retrieved the case this morning and should be on the road tomorrow morning.
