METAR reports observed airport weather; TAF describes expected conditions over a defined forecast period.

A bilateral agreement can define which airlines may fly between two states and under what rights.

A great-circle track is a baseline, but winds, weather, airspace, performance and traffic constraints shape the filed route.

Demand forecasts, aircraft time, airport slots and local sales determine whether a route flies all year, for one season or only a few weeks.

These unusual services let an airline carry local passengers between two foreign countries, adding choice and complexity to a market.
Routes
Demand in both directions, seasonality, connecting traffic, bilateral rights, airport slots and aircraft availability all shape a new route. A short flight can be difficult to schedule if it misses a hub connection bank.
Frequency and arrival time can be as important as distance. When comparing route announcements, distinguish a filed schedule from a service that has started and check whether the airline or a partner operates it.
