If you need to travel on short notice, isn't it faster to book online rather than lining up at the airport?
Or does the airport ticketing desk have a later cutoff time?

In her situation, no. The phone would ring at 5am, she'd get dressed and grab her "go" bag and walk down to the subway, then buys her ticket (usually one-way) at the airport counter.
In theory she could try to book tickets on her phone on the train, but connectivity can be iffy on the train, and buying an expensive airline ticket is not the sort of thing you want to take unnecessary chances with. (Think double-purchases, false purchases, etc...)
