He IS making the efforts necessary...don't be surprised if you hear from him during that five hours, wouldn't surprise me for him to give you a shout. He honestly does appear to be trying to help you through this.
FWIW...I know ALLLLLLL about the fun stuff at the airport LOL. Did I ever mention both my husband and I work in the airline industry? LOL He works for American, I work for a Repair Station.
