Definition: Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Input: What happens if you book tickets through an airline or travel agent, but on the travel date miss a connecting flight (either because the first flight was delayed, or because immigration/security took too long at the connecting airport)? Will you be put on the next flight for free? Are you expected to pay for a new ticket or a change fee? I'm specifically wondering about Continental/United, but also curious about airlines in general.

Output:
What happens if you miss a connecting flight?
