Hi all, I have a question and after searching around for a while on the internet for answers (+ giving up after spending 40 mins on hold to US airways) I've decided to just ask it myself.

Basically I'm scheduled to go to New York (from London) for a week long holiday next month (7 Oct -> 15 Oct) on US airways.

However, I've now found out that work want to send me out to Hawaii a week later, on the 23rd. They're happy to fly me out from anywhere, so I've got a great idea of intentially missing my return flight home, grabbing a quick flight to Toronto to visit family for a week, and then work should pay for my Toronto -> Hawaii and, the week later, my Hawaii -> London flights.

My question is, is this allowed? Will it be on my passport info or whatever that I'm meant to be leaving the US on the 15th; will they care that I'm actually going somewhere else before heading home? I don't want to get to the gate and find out I'm in trouble for not leaving when I was supposed to or something.

I don't really care about losing the value of the flight from NY -> London, since the flight from NY -> Toronto is cheap as chips and my work is paying for the Hawaii flights. I'm just not sure whether I legally have to tell US airways I don't want to fly home with them.

Thanks for your help.
