dream maps

memory of inputs when re-search for flights so dont have to enter them all again

flight search (and allowable destinations) includes all partners (or even better all airlines)

advanced routing options including ability to choose from multiple routes, able to choose which of many flights for each leg to tailor the transits/stopovers

bring up full rules not some useless summary that doesnt include all the info you need

manage my booking function (yup some airlines still don't have this grrrr)
