Final answer:
Pre-arrival services for domestic flights include checking baggage, obtaining a boarding pass, going through security screening, and waiting to board the aircraft, rather than the in-flight services listed in the question.
Step-by-step explanation:
The service flow during pre-arrival for domestic flights does not include collecting trash and preparing for landing, serving a light snack or meal, providing duty-free shopping, or conducting a final security check, as these activities happen during the flight or upon landing. Instead, pre-arrival services for domestic flights typically involve travelers arriving at the airport, checking their baggage, obtaining a boarding pass, going through security screening, and waiting to board the aircraft. This process can be impacted by rate-determining steps such as the availability of ticket agents and security equipment, which can lead to delays and a less efficient boarding process. Therefore, the mention of 'final security check' may refer to the security screening that takes place before a traveler can proceed to the gate area.
