Sorry, Don't know...
July 13th, LH
had a special (we've not seen before in PDX
- doesn't mean it hasn't been at PDX
before) Star Alliance - must be a picture of it here, but did not see it after a cursory glance - anyway, all white with Alliance logo on tail, and a small LH
name on front...
I was out for a time with my boys and know they saw one AS
(pretty sure it was the salmon) take off in the afternoon.
Other than that, sorry I can't be of more help.
