Exactly correct. At smaller airports, it's a waste of time to arrive two hours ahead. Just went through GRR. With NWA's e-ticket kiosks, it took three minutes to check four family members in with luggage. No delay at security. Ditto at PHL.
And if you're flying smaller airlines like Midwest Express, check-in is equally fast.
