Sorry for the newbie question but I read through the wiki and posts here but didn't find the question clearly answered.

I have a companion pass expiring on 8/2015. I have plans to go to Hawaii in 2/2016. I would like to do the following:

1) Book a RT ticket to Hawaii on AS for myself and one of my kids using my companion pass. I will book the ticket in 8/2015 before the pass expires for a flight in 2/2016 since that is less than 330 days later.

2) Book another RT ticket to Hawaii on AS for my wife and another one of my kids using my new companion pass that will appear on 8/2015 (to be expired in 8/2016).

This way I will be booking 4 tickets on the same RT itinerary with 2 companion passes (this year's companion pass + next year's companion pass).

Is this possible?

Rock.
