Having a UA Mileage Explorer card. Will that get one free bags on a codeshare flight which is the leading flight? and then a UA Operated/Marketed flight to follow?
I know where it's a UA Operated flight it would trigger free bags for the whole itinerary, even if there's a codeshare flight to follow. Wondering how it works when flying the opposite way with a codeshare flight to start, followed by a 2nd leg of the flight operated by UA?
