Answer 2

bargain would be difficult, from London to new york you might get some cheap flights, probably 300 pounds or so, try the low cost airlines, I think there's one operating between london and new york which is quite cheap but I can't remember the name. Then from new york try to get a charter flight to hawaii or in the worst case to San Francisco and then Hawaii, maybe you get lucky and can fly for $300 or $400 from New york. I think if you try London-Hawaii it would be unpayable. I wouldn't try from Paris it might be more expensive. Good luck.
