Air chain how are they done?

that’s my question y was trying to do some but i didn’t get anything at all…

air mp,air hp bets for air to air use the mp punch as you usual would then at the moment of contact press hp. this resets them and you land first so make sure to mix them up when they land
air jp, air mk best for jumpin. jump in with jp as usual and hit mk at moment of contact.

Thanks a Lot!!!
