I don't see a merger happening any time soon at UA. Definitely not Frontier. DOT would take issue with the United monopoly in Denver. Last I heard UA already had 40% of DEN flights and SW had 33%.
On anther note, all things 787 now has a UA delivery date for the 787-10 in 08/18! Now, if we could just get a replacement for our aging 737-700's and 319's. Maybe 50 of the technologically superior CS 300's? Also, let's go ahead and trade out of the 100 Max 10's for 100 797's and buy 100 A-321NEO's. United, PM me if you need help with the fleet plan. I'm here to help.
