I've been bumped on Friday afternoon flights 2 of the last 3 weekends on United. The first was Chicago to Oakland, and the second was Columbus to Chicago (though the continuing Sacramento flight was sold out, too). In both cases I was rerouted on my original carrier, and arrived within 1-2 hours of my original flights (though they flew me to SFO instead of OAK). $400 vouchers for each. If anything, I may try to line up more of my flights to get me home on Friday afternoons.
