Thanks for the tips! Checking into Norwegian now (also found AerLingus as an option from Boston if I can position myself that way).

This might be a good meta-topic btw - how to go from [one region] to [other region], where regions can be Western-US/Eastern-US, SouthAmerica, CentralAmerica, WestEurope/EastEurope, NAfrica/SAfrica/EAfrica, MidEast/India,EastAsia, Australia.

Does such a chart exist, because it would be very useful e.g. I recently found that tons of cheap middle-eastern airlines if your regionA to regionB can use a mideast connection in the routing.
