I've got 955 tier points with a collection year enf of 8th May, so I'm looking for a way to pick up 545 in April, in the process hitting gold and having those 545 also count towards next year. Any bright ideas would be much appreciated. So far I've come up with the following possibilities. First, there is the simple but dull possibility of doing lots of NCL-LHR returns at around £160 each so £2 per TP. There are various other domestic jaunts which earn at a similar rate.

More adventurously, there is this, which would tick it off in one go with some to spare, but is more like £3/TP:


I've also seen this, which note is in premium economy rather than business. My thinking is that it might be possible to optimise the routing and collect close to 400, which gets me most of the way there at around £2/TP and I can pick the rest up domestically:


I don't have scope for a longer trip to make use of double TPs, the aim is to do it over a weekend with as little time off work and hotel nights as possible. I've looked at longer EU trips as well but couldn't find anything decently priced, going East also didn't look very promising. All ideas gratefully received.
