Recognizing which items are returnable crew assets versus informational materials helps you see what’s expected. The inflight service newsletter is an informational publication provided to crew for reference and does not function as a piece of equipment or credential that must be surrendered, so it isn’t listed as something to be returned. In contrast, the Flight Attendant Manual (Manual#610), the Known Crewmember barcode card, and the parking pass are issued items or credentials essential to operations and access, and they are expected to be returned when you’re done with them or when your assignment ends. So the item not listed as something to be returned is the inflight service newsletter.

During flight, the Pilot in Command has full operational control and authority over the crew to ensure safe operation. This means the PIC decides how the flight is conducted, directs the actions of the crew, assigns duties, and can approve or change procedures and the flight plan as needed. The authority isn’t limited to navigation; it covers all aspects necessary for safe aircraft operation, including handling abnormal or emergency situations. Ground supervision cannot override the PIC while the aircraft is in the air—the PIC remains the final decision-maker until landing and responsibilities are transferred. If a crew member’s action could affect safety, the PIC can immediately direct a change to ensure safety.

When a Mesa flight is operating as a codeshare, the cabin pet rules come from the operating carrier, not Mesa. So the number of pets allowed in the cabin on that flight follows the partner’s policy for in-cabin animals. In this scenario, the limit is five cabin pets per flight. That means up to five small dogs or cats can travel in the cabin, as long as each pet is in an approved carrier that fits under the seat, and the passenger adheres to all related requirements (advance notification, applicable pet fee, health documentation, and any route or aircraft restrictions). If a particular flight or destination has additional constraints, those would apply as well, but the maximum allowed in cabin on codeshare Mesa-represented legs is five.

Linear inches is the total of a bag’s exterior dimensions: length plus width plus height. For carry-on baggage, airlines typically cap this total at about 45 inches, with a common size example being 22 by 14 by 9 inches (22 + 14 + 9 = 45). So the largest carry-on that can pass this standard is 45 linear inches. Bags totaling 50 or 60 inches would usually be rejected at the gate, while a 40-inch bag is within the limit but not the maximum.
