Thanks for the info! A follow up question: how many extensions do they normally allow (provided it's more than one)?

As long as you keep calling and extending the reservation, there's no limit. Be sure when you get close enough you ticket 21 days prior (the agent should mention this and extend to that point unless you don't mind paying the processing fee)
