last year my sister in law and her husband and their grandkid were looking to come up here from Rio. She had enough miles for the adults but not the kid. The kid and his mother were here five years ago. they didnt even know they had FF miles. I kept records of the numbers and passwords. They had no activity since 2005. i was able to shift all their miles into my wifes account who is silver elite. We got the kid a ticket for the cost of the transfers. He got to see a Rockets game, ice hockey game,rodeo and Cowboy Stadium. Plus they saw me officiate a HS girls game involving the Gatorade National Player of the year.Had a grand time as they didnt want to stay in Rio during Carnival(they live there and have seen all that). so the 18 months didnt mean much.
