Which airline is best n economical?
There's no such thing as 'best and economical' airline. Throughout the year, the cheapest fare will keep on changing from one airline to other. So, if your priority is price, then I suggest you go and check www.ixigo.com You can check prices on it from makemytrip,expedia,via,and few others, all at the same time.
Now, if your priority is baggage allowance then just to let you know, you will normally get an allowance of 2 pieces of 23 kgs each+ 1 piece of hand luggage upto 8-10 kgs+a laptop bag. If you want more baggage then I suggest you specifically look towards Jet Airways.
As far as your journey is concerned, don't try to book a flight route with too many connections or a connection of a very long duration, unless that saves you a lot of money in comparison to a comfortable journey route. It's just not worth saving a few bucks if it means you have to spend hours and hours at any airport for a connecting flight.
Hope this helps, good luck!
