Sled, you are wrong! Not until SLI and that could potentially be a year from DOS. Here is an example from the MEC update:

Scenario 3: Twice-furloughed pilot now working at CAL. Three years UAL, then another two years UAL, and 1.5 years at CAL.

At Date of Signing, the pilot will be adjusted to 4 years 7 months of longevity for pay purposes at CAL. This longevity will be improved after SLI by combining his UAL and CAL longevity. Additionally, for pay it may be improved by the SLI process as described in Scenario 2 above. This UAL furloughee working at CAL is considered a “CAL pilot” but is pay protected at his UAL pay rate. That pilot will see a potential increase in pay longevity to 5th year TA rates if the new rate is higher than the previous protected rate. After the completion of the ISL a second adjustment of his pay longevity will be computed to account for his time on furlough. This added pay longevity will be capped so as to not exceed the longevity of the CAL pilot just senior to him on the ISL. This pilot will NOT lose any longevity and can only improve upon his 6.5 years of longevity for pay. After ISL this pilot’s full earned longevity (CAL plus UAL) will apply.

And notice they don't even use a good example. We have guys who have over 7 combined years with UAL and time at CAL who will be paid at 4.7 years until SLI. Might not be looked at as a bid deal because it's a pay raise over the old protected United rate. However, it definitely doesn't allow for any further credit for time on furlough. Now, why then, did they generously give credit for time on furlough to the majority of the CAL guys and all of the 07-08 UAL hires? I guess it was just out of the kindness of their hearts.
