When AA acquired TW, it incurred very little pension liability for the TW employees as most of the employees were entitled to TW retirement benefits specified by the PBGC. However, those TW employees who continue to work for AA will begin accruing from date of hire. For instance a 35 year F/A for TWA would be receiving a pension from the PBGC and would be entitled to a pension from AA for the two plus years s/he worked at AA. Something like $75.00 per month.
