i agree with the second part of his advice but no the first part.
Say for ex. if i have to book a tatkal ticket for 11011 from Pune to KOP for 13th so shall i book it today? in IRCTC first it wont allow to pull data for the 13th tatkal and then i try to book form LNL and then change the boarding point it wonr allow? Please explain if i am confused?
