I’m always looking for some interesting routings to burn some miles and here’s one I found:

UA7644, an E70 departs IAD at 12:25 ET and arrives into Halifax at 15:40 AT. Then departs at 16:43 as UA7625 and gets into ORD at 17:55 CT. I probably would return direct to IAD as the reverse routing overnights at YHZ.

Wonder how much suspicion I would raise clearing Canada Customs then going immediately to US Customs (Halifax has US Pre-clearance) Would the 1 hour layover be enough time? And can it all be done on one North American 50,000 mile award?
