Here are some handy tips to help you book confirmed Tatkal tickets quickly.
Use multiple login credentials; Enter passenger details in advance
Use multiple credentials: One simple trick is to open multiple browser windows and try to book the desired Tatkal ticket using different login credentials, as this will increase your chances of getting a ticket.
Enter passenger details beforehand: Always fill in the passenger details prior to the opening of Tatkal ticket bookings. This will help save time, and increase chances of getting the ticket.
Keep IDs ready; Choose 2AC over 3AC
IDs: Keep important IDs like PAN or Driving license ready at your end to avoid wasting time looking for them at the time of booking.
Choose 2AC over 3AC: 3AC tickets tend to get exhausted much quicker than 2AC, so always prefer Tatkal tickets in 2AC, in order to save time, and better your chances of getting confirmed ticket.
Avoid Tatkal-exhausted trains; Go for netbanking
Avoid Tatkal-exhausted trains: Do not waste your time trying to book tickets in trains for which Tatkal tickets have already been exhausted.
Go for netbanking: Entering lengthy debit/credit card details can lead to unwanted wastage of time. That's why, it is advisable to stick to netbanking as your payment method for Tatkal bookings, as it is the fastest mode of paying on IRCTC.
