I personally would use Jet Airways for any domestics etc from India.

If you are paid in the Uk then you will need your company payroll (tax specialist) to do something called tax equalisation for you through a self-assessment. While a pain, it is the easiest way to get things done, it also avoids you having any currency problems eg the Local currency bombs and you can't afford to come home.

Do you get a monthly allowance as well as your salary? If so, get monthly allowance in local currency paid into a local bank and salary into your uk account and try not to touch your salary.
