I'm not sure if this is mentioned, but if the MTA wants better express service, my proposal will be to run buses anytime of the day (at least 30 minutes). This especially includes the QM21 from Baisley Park, the QM3 from College Point, and the QM24/34 and QM25 from LaGuardia.
Also regarding about the Queens bus redesign, I am concerned on how express service will remove many stops, in order for the MTA to have flexible service. An example would be that I rode on the QM6 back to Manhattan from LIJ Hospital. During my ride back home, there was no one on each stop after LIJ, making it feel like a Super Express. The routes should also not cut back times, and rather do 24/7 bus service, just like with other local/limited routes around the city. I don't know if the idea would be perfect, but this is just my proposal.
