My flight was cancelled this morning. Apparently the Omaha airport is reducing landing slots today, possibly due to a forecasted high of 4 degrees (F) impairing operations. It took quite a bit of time, and some very pleasant talking by me, but I’m rebooked on two other airlines through Denver (gah!), with a very long layover there, then on to Omaha a couple of hours later than planned. All this assumes further cancellations are not in order, and weather doesn’t worsen all the way around.
