I just achieved platinum status with Marriott Rewards and am hoping to utilize the RewardsPlus setup to get Silver Status on United Airlines. I signed up, but was informed that the process could take 7-10 business days!! However, I'm traveling internationally with a toddler (20 hours total travel time!) on April 11th and for obvious reasons the economy plus seats on United Airlines would be tremendously helpful. Any advice would be greatly appreciated!!
