prompt:
A ticket bought at 22:30 for a 06:00 departure exactly 14 calendar days later fails a 14-day advance purchase.

Input {'res','ticket','depart' ISO local datetimes,'ap_days','ticket_within_h'}. Ticket before reservation -> 'ERR_ORDER'. AP counts calendar days between the ticketing date and the departure date (>= ap_days passes) and is checked before the ticketing time limit; ticketing must be at or before reservation + ticket_within_h hours. Return 'PASS', 'FAIL_AP' or 'FAIL_TKT_TL'.

Tickets issued at exactly reservation plus 24 hours fail the ticketing time limit.

Input {'res','ticket','depart' ISO local datetimes,'ap_days','ticket_within_h'}. Ticket before reservation -> 'ERR_ORDER'. AP counts calendar days between the ticketing date and the departure date (>= ap_days passes) and is checked before the ticketing time limit; ticketing must be at or before reservation + ticket_within_h hours.

prompt:
A 24-hour ticketing limit allows tickets issued three weeks after booking.

Input {'res','ticket','depart' ISO local datetimes,'ap_days','ticket_within_h'}. Ticket before reservation -> 'ERR_ORDER'. AP counts calendar days between the ticketing date and the departure date (>= ap_days passes) and is checked before the ticketing time limit; ticketing must be at or before reservation + ticket_within_h hours. Return 'PASS', 'FAIL_AP' or 'FAIL_TKT_TL'.
