Perhaps we should just answer 'Honolulu' as the answer to any TP run related question

For 410 TPs I'd look at a CWLCY return. LCY-JFK-LCY would get you 420 TPs and you could spend some time in New York.

Doubt that's the cheapest option, particularly at such short notice (if you have time see if it's cheaper by starting at DUB).

All the other options in that timescale seem too much hassle as most shorthaul CE gets you only 40 TP and the longer ones (like HEL) get 80 but take up more time.

You'd have to spend a lot of time hopping around Europe whereas a trip to New York would get the points more easily.

Note: I don't think CWLCY operates on a Saturday so you'd need to fly on Friday, but I don't think any other options would not require taking some time off work.
