Question

how many hours from like 1-24 and more would be reasonable for first class flights?

Answer 1

The number of hours for first class flights can vary significantly depending on the destination and airline. Generally, flights that are longer than 6 hours are considered to be first class flights, as passengers are provided with additional amenities and services to enhance their travel experience. Some first class flights can last as long as 20 hours or more for ultra-long-haul routes. Ultimately, the number of hours for a first class flight will depend on the specific itinerary and airline chosen by the passenger.
