if you go to the loews site, click on the link for more info on requirements.
i copied two of the requirements for you.
if you don't use your loews membership within a 12 month period, you might be considered an inactive member.
to stay at the platinum level, read #12 below.
your stays must be within a 12 month period.
since you have not been at a loews hotel in over 48 months, you might have been dropped or your level might have been reduced to gold or blue.
you can call loews direct and give them your membership number to find out your status.
5. Loews reserves the right to terminate the entire Program with six months' advance notice to all then-Active Members, and immediately upon notice to all then-Active Members in the case of a termination relating to the substitution of a similar replacement program. You will be considered an "Active Member" so long as you have stayed in a Loews Hotel during the previous twelve months.
12. LoewsFirst Gold membership requires three (3) qualifying stays or six (6) cumulative nights (associated with a qualifying stay or stays), in a single Loews Hotel or any combination of Loews Hotels, in a calendar year. LoewsFirst Platinum membership requires ten (10) qualifying stays or fifteen (15) nights (associated with a qualifying stay) in a single Loews Hotel or any combination of Loews Hotels, in a calendar year. A calendar year is defined as January 1 through December 31. Retaining membership in LoewsFirst Gold or LoewsFirst Platinum requires meeting the respective criteria for LoewsFirst Gold or LoewsFirst Platinum each calendar year. LoewsFirst members who were LoewsFirst Gold or LoewsFirst Platinum members prior to June 1, 2003 will retain that status through December 31, 2004, unless a higher status is achieved based on the above stated criteria during the calendar year 2003 or the calendar year 2004. LoewsFirst Blue members and new members will become LoewsFirst Gold or LoewsFirst Platinum members when they meet the above stated criteria. Once a Member attains a tier level, this level will remain in effect through the end of the subsequent calendar year. Post-enrollment stays recorded beginning January 1, 2004 are eligible toward tier-level qualification for the calendar year 2005. Thereafter, Members must requalify each year for the following year's membership.
13. In the event you do not remain an Active Member (as defined above) your membership may be cancelled at the sole discretion of Loews.
