Have no idea who this is but answered 1 time since I have friends with 206 431 #s

I just had two missed called from this number, called back and it said not in service.

I found out it was my husband calling from Alaska Airlines at SeaTac. He told me that it is a generic number used by Alaska Airlines, just as am outgoing number only.

Caller hung up before I could reach phone
