Hello - this is my very first time using the Alaska Companion Pass, and I'm a bit confused.

I'm trying to book a reservation for 3 pax: me + spouse + kid. Obviously, the companion pass applies only to 1 pax, but still the UI tells me that I'm only allowed to have 2 pax on the reservation.

Does this mean that I must book two reservations? One for me + kid, and one for spouse? This feels kind of weird, so I'm wondering if I'm doing this wrong.

If I do need to book two reservations, using my Alaska Visa card will my spouse get 1 checked bag free?

Thanks!
