Don,t believe 28 is too old personally.I started flying at 27 and within 4yrs only have ATPL to complete before approaching the regionals/airlines.Seems to take forever clocking up those hours,but i look at it this way-i was paid(admittidly poorly)to see Australia,i think i,m very lucky?.It,s an amazing learning curve this industry and does take time and $$$ to get there,but still can,t think of another job i,d rather be doing!.Goodluck.
