Unfortunately for us we have to travel during peak weeks i.e. school vacation weeks. Since we both had enough points in our accounts I figured I'd open our accounts in two different browsers and book at about the same time. My page showed tons of availability in both main cabin and first class. Mrsderby44's showed zero flights. I ended up transferring points from Chase to United--problem solved--the first class numbers were too high so I booked main cabin. An example of having lowly Silver can make a huge difference. So using points to maintain Marriott Platinum status worth it to us.Happy travels and best of luck to all.
