Looking for a good website to purchase flights and also travel insurance for out of country. 

 For insurance:  www.travelguard.com

I'd recommend booking your international flights directly with a major airline. If you book with a third party it gets complicated and frustrating if there are delays, cancellations, etc.  When traveling international, you want to always have access to the best assistance possible.
