In the movie “All the President’s Men”, the vice president says that at the airport. What does it mean? What is “the other ticket” referring to?

The other ticket refers to the candidates of the other party who are on the ballot.
A party presents a certain set of candidates for election to a given set of offices. It has a certain number of nominees but these are insufficient. Which party candidate is present in the election? If a ticket is a ticket for another person, it is a ticket for another party. When there are only two main parties, it is clear what the other ticket is, relative to either ticket.
Presumably, the Vice President was speaking about someone in his own party who showed some sympathy for the other party, or at least the other party’s offering in the given election – its ticket.
In addition, in US elections, a party presents a candidate for elected President and Vice President, and they run together, as a single ticket
