As of 2015, customers can only make Megabus reservations through the company's Search & Buy tool on its website. Customers reserving a bus ride through the Search & Buy tool are required to enter the number of passengers travelling.
Passengers who reserve a Megabus trip under the same reservation number must board the bus as a single party. Megabus passengers who are bringing more luggage than allotted by their reservation must also purchase additional reservations to accommodate their extra bags. Once the customer completes a reservation online, Megabus sends a confirmation email through WorldPay, as well as a reservation email.
