In contrast, if (for example) a Continental B739 at Houston breaks down, it's far less likely that they will be able to absorb the loss and find you another plane just like that. You're likely to have a very long delay or a cancelled flight.
How do you figure? CO has over 150 738/9s in their fleet and a decent number of them at IAH at any given time. I've had them locate an alternate plane for me at IAH at least once. And our replacement wasn't broken when we got there.
