The main differences between the classes are the comfort level and seating arrangements. In 1st class, passengers enjoy larger, more comfortable seats with more legroom and space for luggage. There are fewer places per row, offering more privacy. The seating arrangement in 1st class is usually 2+1, meaning two seats to one side of the aisle and one on the other. In 2nd class, there are usually two seats on either side of the aisle, offering less space and privacy. Although 2nd class seats are still comfortable, they are not as spacious as those in 1st class. Both classes offer access to the on-board catering service.
Excellence Class is the luxury option, offering the highest level of comfort and service. The seating arrangement is very generous, with only 20 seats in the entire carriage. A gourmet catering service, complete with a multi-course menu, is included, as are access to an exclusive bar-lounge area, a personal concierge service and onboard entertainment.
