Wow....quite a few CO no-no's on this one.
1. CO doesn't like to print paper tickets. They would much rather you wait around for 30 minutes while the agent calls the helpdesk trying to figure out how to reissue it electronically. 30 minutes is nothing, as etickets "save money."
2. CO doesn't like other airline reroutes, especially in situations where it wasn't CO's fault. Unless your ticket was refundable, I doubt the agent should have done this.
Was there something else to the story? Perhaps you made it technically on time, CO was overbooked, and they just took care of you without any denied boarding compensation?
I don't know, but this story just sounds out of line with what CO would normally have done: "Sorry, you missed your flight, the next one with space is 3 days from now. How about going home on Friday?"
The reason is, if you can figure out what that something else is (if there is something), then you can use that as grounds for original routing credit.
