MX ratio below 50%

I just got a plan with 49% MX, scheduled some flights hoping that in the next day the ratio will go up after some Maintenance but nothing, been 2 days now and all flights are getting canceled. How do you get around this? 3 days in advance scheduling? 

You need to transfer aircraft manually to the station where it will depart from, it will then automatically undergo maintenance.

Cheers!
