Thank you again! I think we have selected our choice. It is through Alaska Air, but two of the legs are actually American Airlines. We have a minimum of two hours at each layover to allow for our baggage to catch up with us.
My 86 year old mother will be traveling with us, so we decided that two stopovers might be better so that she (and we) have time to walk around a little every few hours.
The nice part is that we can select our own seats.
Have a good week and thanks again for your help.
