June 9th: CO262 (YVR-IAH) - 3 empties out of 12 on a 733; the first empty seats in F I've seen on CO in years - a shame I used miles to upgrade myself and a friend.
July 6th: CO1097 (IAH-LAS) - 10 or so empties out of 20 on a 739; saw that when checking the incoming flight for our outgoing CO296 (LAS-IAH) which was full in F with only two upgrades. Neither is probably surprising for the Sunday after 7/4.
