Osaka to Kansai airport early morning?

Hello all,

I was wondering what my transportation options are early in the morning (5/6am arrival at airport) from Osaka? I've noticed trains aren't running to arrive there so early and have not found any info on bus transportation.

I was considering a taxi however this is only an option if I have money left over at the end of my trip - I would rather a cheaper option anyway.

Any tips will be appreciated. Thanks

Where in Osaka City will you stay?
By what time do you have to reach KIX?

A few buses are scheduled
to depart from Umeda area and arrive at KIX Terminals 1 and 2 before 6 in the morning;
however you cannot book your ride,
which means the seats are secured on a first-come, first-served basis.

Unless you alternatively choose a later fight,
it sounds better to stay close to the airport for the previous night.
