Yes, booking with payment upon boarding is available for most routes. There are exceptions: during periods of peak demand, carriers introduce prepayment, and some carriers also require partial prepayment (with the balance paid to the driver upon boarding).
Please note that full online payment on the website has an advantage, as it 100% guarantees your seat (during extremely high demand, carriers may prioritize passengers who purchased tickets in full, canceling tickets for those who did not make a prepayment). Therefore, online payment on our website is a more reliable choice.
