I've just booked SLC-DFW-JFK in Y on a Sunday morning in April with a 41 minute connection in DFW. I know 40 minutes is MCT and I've put myself in the bulkhead row in economy with a request to upgrade in the hope of getting off the plane as quickly as possible. I'm Platinum so hoping I would be protected in case of a misconnect, but I know I'll be competing with much higher elites at DFW. Bad idea?
