Hey MidWestDave,
First off, thanks for signing up, giving us a try and giving us feedback! Glad that our layout was able to help you search for flights easily based on your preferred mileage program.
As for your questions, we have some good news...
Our product and development team are currently working to address both of your comments...
1) We are developing a feature that will allow you to see flight results for multiple days.
2) As for British Airways, our product team is working on integrating their flights into our back-end system and should also be released soon.
We are a bit backed-up right now with all the feedback we have been getting from our members but we will make sure to notify the forum and our members via email once either of these pushes go live.
If you have any other comments or suggestions, please feel free to post them here or email us.
Thanks!
