If you’ve ever booked a flight or planned a trip, you’ve probably come across the terms domestic and international flights.
But what exactly do they mean, and what are the key differences between them?
Even if you’re a first-time flyer, a student planning to travel, or someone just curious about air travel, understanding the difference between these two flight types is important for a smooth and successful journey.
What Is a Domestic Flight?
A domestic flight is any flight that starts and ends within the same country. For example:
- Flying from Lagos to Abuja (within Nigeria)
- Flying from New York to Los Angeles (within the United States)
Domestic flights do not cross international borders and are usually shorter in distance and duration.
What Is an International Flight?
An international flight is a flight that crosses the borders of one country into another. For example:
- Flying from Nigeria to the United Kingdom
- Traveling from India to the United States
These flights involve multiple countries, and usually require passports, visas, and customs clearance.
