Why? Do we have any hard data that RJ flights are more likely to be cancelled LGA-ORD than others? Having flown on them twice -- both in E+ -- I was pleasantly surprised at how much I preferred the smaller plane, even without sitting in an exit row. Now that F meal service on this route has been cut back to a deli plate anyway, what exactly is being sacrificed? Heck, I'd take 1CD on the EMBs over any 735/319/320 F seat in a heartbeat...
