Here is some more crux:
Even though the use of STV's is so limited, I understand many pilots are concerned about the possibility of being inversely assigned to an STV for a long period of time. While the Company may use STY's of up to three bid periods, we are prepared to limit ourselves to one month for those pilots who are inversely assigned to an STV. However, we will agree to this change only if this is the only modification the parties agree to make to the LOA. If this is an acceptable approach, please accept this as the Company's written commitment that the language in the HKG/CDG FDA Letter of Agreement will be considered modified accordingly. If you find this modification acceptable please sign below and return the agreement to me. We realize that the entire LOA even with this modification remains subject to the ALPA ratification process currently underway.
It doesn't sound to me like this was the plan all along.
