THANKS. Let's say there are 4 members as part of this program. Member 1 (husband) earns 36,000 tier miles, member 2 (wife): 10,000 tier miles, members 3 & 4 (son): 0 tier miles each. So, really member 1 is silver, but if they are in the same account can't members 2, 3, and 4 also avail of silver priviliges (lounge in particular) if they are traveling solo. What happens if all travel together? All will be entitled to lounge access, correct????
