Only point you are missing here , the topic is of 2A/1A AC class train vs flight tickets. Its very much cleared in many cases flights are chepaer now. Even for 10 days before also flights in many sectors now cheaper than AC class.
Regarding train travelling maza, ya may be for some. But may nit be for some. It depends, because a family caring a little baby in a train for 30 hrs is much much difficult for them surely train journey head ache. Like that there are many cases.
