You could build a biggish airline playing 30 min/day before, you can again now. Especially if you're joining an existing world, not starting from day 1. You just have to take a look at the UM and production lines, then pick a fleet with good availability. e.g. if you join the 1997 GW, plenty of BAE-146 for medium jet, dash-8 for turboprop, DC-10 if you want LH, etc. If you join the 1950s GW, there's a practically endless supply of DC-4, but you'll get hardly any DC-6 if you just log in twice/day.
