Since you are such an economic "expert," why don’t you put in the necessary time and effort to dissect each concept contained within the 290 pages of this TA and determine the appropriate values for the other work rules and benefits which were not only preserved, but dramatically improved as part of the contract--you know, vacations, PTO days, schedules, hours of service, MOB health insurance, crew bases, the grievance process, scope, etc., etc., etc., all of which represent a new-found control of our work-lives as pilots at Flight Options. Once you do that, perhaps even you will see that the impact of the "loss" of the 401(k) match, which was previously at management's sole discretion to take away, pales in comparison to all the intangible economic gains in the contract, to say nothing about the tangible ones, such as the salary increases, job protections, work rules and QOL improvements.
While you ham-handedly attempt to compound the loss of the 401(k) match, you don't calculate the cumulative value of the various salary increases over five years, which could be worth 60 to 75 percent of your current salary, not including the compounding effect of the time value of money. Also, inflation, which is now at historic lows, typically runs in the 3.0 - 3.5% range.
