All of your examples apply equally to both A and B (since we don't have any other information about the differences between A and B) and thus have no impact at all on the expectation about the difference between future cost or easiness or benefit/utility of the travel to A versus B, so these arguments can and should be ignored.

On the other hand, the previous price is a signal that does provide some information about the differences between travel to A and travel to B and allows to make a better-than-chance decision than treating both options as equal.
