It could be the last minute jitters setting in..3 weeks! But I have a Boyt double rifle case...80 linear inches. United's limit for standard checked luggage is 62 inches. More than this.... $200 charge. I called the folks at United to ask them about the situation and how strictly it is monitored..as you. Old guess I got little for info. The counter at the aiort we are flying from does not take phone calls...I'm trying to see what I can do in advance to try and mitigate the charges. I'm afraid I will be at the mercy of the person working that day. What has everyone else experienced at the check in counter?
