HI
When I was in New York in February of this year, there were flags all along 34th street advertising the Westminster show which had been on the week before. I believe its 13th & 14th Feb next year.
As for cheap flights...not sure but I think Virgin Atlantic are usually quite reasonable (we fly from Dublin with Aer Lingus, usually) but I'm sure a quick trawl of the internet will turn up the best deals. The sooner you book, the cheaper you should be able to get it.
Ooh, I'm quite jealous....I love New York (shopper's paradise) but be warned...it is very likely to snow. I saw more snow there in a week this year than I have seen in my entire life!! But it was lovely all the same :)
Not sure about therapies as I'm not a nervous flier...just an impatient one!! I'm sure someone else will be able to advise better.
