If you are trying to maximise TPs, and you are OK to arrive a day late you could try and simply rebook everything from London onwards by up to 24 hours later. Getting to JFK tomorrow won't be difficult. What you need to decide is whether you're OK to forsake 80 TPs by taking the direct Finnair service from HEL to JFK to get back on schedule there; or alternatively do something like HEL-BRU-LHR and then rebook from London (probably meaning JFK-PHX is the next day). If maximising breaks is the key, yes, suggest alternatives to the agents, mostly they'll go along with anything sensible so long as it isn't too far off the line.

Also note the possibility of Finnair getting back on schedule overnight if they find another aircraft/crew.
