Iberia Airlines Iberia Plus - LAX Non-stop to MADRID only on certain days?

I have redeemed AA miles for this flight but unfortunately need to change to one day earlier but the non-stop is not offered on all days.

Anyone know if this will eventually become a daily non-stop from LAX ? I have a months until travel in November.

The current summer timetable shows non-stop on M, W & F only.

Looking at a previous winter timetable IB only offered W or F.

So I think it is very unlikely that you will see an increased frequency! :(

I see MW and Saturday serivice! But why is it, there are no flights on Aug 4 and 25?

This flight has normally flown (seasonally) 3 ~ 4 times weekly, iirc. It is not likely to fly daily at any time in the near future, particularly IMO with the IAG ownership of BA and IB and Joint Business Agreements between AA, BA and IB.
