the air time for a 28,29 and 30 byte packet is the same

Ah, @cslorabox explained:

@cslorabox

there is granularity imposed by the 4/5 coding - the actual airtime doesn’t increase with each byte, but rather jumps each time a new coding group must be added, so you “pay” in airtime for the number of coding groups sent, even if the last one is only partially filled
