I have been following airwaysim since quite a few hours . I have always felt that passenger demand in ASIAN countries especially India is very much unrealistic . India is 3rd largest domestic aviation market after USA and China .Then why demand is so less in airwaysim ? I expected that this would be made realistic after last few updates ? Delhi airport is among world's top 10 busiest . India has 138 operational airports but in airwaysim this no is very less . Is there any particular reason for constantly ignoring this stats ? are this going to improve in due course ? It seems European airports definitely enjoy an advantage . Any suggestions ?
