domestic flights from Delhi...

As said before the inland flights start from Palam airport..
this used to be the international arrival airport once..
best domestic airlines are nowadays Sahara air and Jet Airways..
Deccan en Jagson are newcomers..the old timer Indian airlines
still is a market..but the competition race is very sincere...
flying within India is not bad..it's quick...and if you know where
you wanna go..it's not so bad either..saves time..but not money..
I'll give you peeps some websites about domestic airlines..

www.jetairways.com
www.indian-airlines.nic.in

I bet you will find your pick in these flights..
I flew with Jet Airways..Sahara Air..and Indian Airlines..
