Max Duty Time Limitations

Date: July 22, 2022

Often a topic of confusion & discussion is determining our maximum actual duty day and the time at which the door must be closed to remain legal for the specific flight to which we are assigned.

Let’s review the maximum duty time legalities found in Section 6 - Minimum Pay and Credit, Hours of Service, and Contractual Legalities which provides for the following:

Domestic Maximum Duty Time

The above duty time provisions are based on the Flight Attendant’s Home Domicile Time (HDT).

*Limited to no more than seven hours (7:00) flight time, unless the duty period contains a single segment, in which case the single segment may exceed seven (7:00) hours of flight time; ground time no greater than two hours and thirty minutes (2:30) and no more than one flight segment after a red-eye flight. A redeye flight is one with any portion scheduled to operate from 0200 to 0400, local time.

**A High Value Trip (HVT) shall be limited to a single duty period starting between 0500 and 1859, containing no more than three (3) flight segments with a total flight time of nine hours (9:00) or more.

International Maximum Duty Time

Under no circumstances shall a Flight Attendant be required to remain on duty, without her/his concurrence, in excess of the applicable maximum hours shown in the charts above, including deadheading.

Calculating Legalities

Below is a simple formula that applies to all domestic duty times and all international duty times with the exception of the “Non-Stop 12:01 or over” category which is calculated in the chart above. 

Maximum Actual Duty Time __________________

Subtract Scheduled Duty Time - __________________

(This number represents how much time we have to play with before we go illegal*)

Add Scheduled Departure Time + __________________

Equals Time You Go Illegal = __________________

*As a clarification, because we may become illegal for a specific pairing or duty period does not mean that we may not be eligible for subsequent reassignment to a duty period for which we may be legal. For example, while there might be a circumstance where one could become illegal for an international flight, it is possible that one might be reassigned to a shorter domestic flight that can be concluded within the contractual duty time limits.

Additionally, when we become illegal to complete the flight assignment, within the contractual duty time limits for the duty period, we may be asked to remain with passengers until a replacement crew arrives planeside provided the company complies with the holding time limitations of our Contract.
