I lost the pay for a OTP trip because I couldn't make it up in the two month window. Sure, I could've flown the SUB trip when offered, but it was tacked on to three days in a row of Burbank-MEM hub turns. No thanks. I figured it'd be easy to make up it up over the next two months. Wrong. Next time I'll take the SUB trip. What's the point of even having that option in the contract if it's next to impossible to get a 6 hour (or longer) trip in open time? On the upside, APT STDBYs are always available for those willing to roll the dice.
