Some will see layinlow as not a member of the club anymore, (although technically he still is).
If I remember correctly, he took his money under some early out deal with the company for FE's and ran as mentioned by other Polar members (Heilvair (?) mentioned it a couple of times on past threads and it seemed to mean something in his response). So I'm not certain of his recall rights.
As to involuntary day extensions, the company has used them to enhance scheduling instead of the agreement that they would only be used for broke A/C or WX delays. There are a load of unfinanced by ALPA grievances waiting for arbitration on that alone. A lesson that should be well addressed in the current negotiations.
