While in the air, holding "down" while pressing "A" will enable Kirby to do a short hop! This move, usable once before reaching the ground, can allow some extra air time to adjust height and maintain horizontal speed. For gaining height quickly however, floating is still a better option.
Those who want a more traditional moveset will be happy to know that this move can be toggled on/off in the options menu, so you can play this game however you want!
