Exactly dost...sabka apna apna convenience hota hai...agar aap 3-4 mahine pehle ticket book nahi karaa paate to isme kisi ki galti nahi hai...aur Railways har tareeke ke logon ko ticket book karaane ki facility de rha hai...this is totally fair..agar aapko normal fare chaahiye to 3-4 mahine pehle book karo aur agar last moment me plan banta hai to bhi we have option of tatkal and PT...obviously paise to jyaada dene padenge ...yahi funda airlines bhi use karti hain.
Aur sabse important baat...flight ki ticket jo PT se sasti padti hai ..vo special fare vaali ticket hoti hai jise kam se kam ek mahine pehle book karaana hota hai...ek din pehle ki flight ticket normally PT se mehengi hi hoti hai.
