Specifically to New York (possibly from Manchester).
I have a big birthday next year and have already booked the hotel (free cancellation in case this shit show doesn't let up). Due to my single/child-free/pretty-disappointing-friends status, I tend to travel alone quite a bit and always choose the cheaper end option, so have splashed a bit more on the hotel.
Which has led to think F it, I'll splash out on the flights too. I've never been whisked away on holiday or treated to anything special in my life so I'll just continue to treat myself! I'm only 5'3 so economy has never been much of a problem but I upgraded to the bubble area the last time I flew to NYC and even that felt more special, despite still being economy.
So, is it worth it, especially for a solo traveller? I'm guessing you get access to a lounge and all that jazz.
