The difference between senior citizen tickets and preferential tickets mainly lies in the applicable objects and preferential policies. Senior tickets are usually provided for senior citizens who reach a certain age. They can purchase tickets with valid documents such as ID cards and enjoy preferential fares. Preferential tickets may be targeted at more types of groups, such as military personnel, disabled people, students, etc. They can purchase tickets with preferential policies due to their special status or age. Specific to preferential policies, there may be differences in fare reductions and travel time restrictions between senior tickets and preferential tickets.
