For last minute travel, F is often similar in price to Y. Sometimes it's even cheaper.
There is also a certain comfort in having a fully refundable ticket (doesn't apply to all F fares, applies to Y), you can say "No, I don't want to fly today." to the TSA dudes.
I never thought that I'd actually pay for F, but yet here I am (done it once, cost me < $70 extra for > 1000 mile flight).
