Konkan Kanya is quite punctual I presume. So I feel I will be safe to have a connection with Pushpak Express which departs CSTM for Lucknow at 8.20 a.m. I would like to know whether I should book on IRCTC site, or can I get benefit of telescopic fares if I book at counter. Can I know the approx cost considering telescopic fares in 1AC, 2AC and 3AC for MAO-CSTM-Lucknow Jn? Will the savings by booking a through ticket at the reservation counter be tangible?
