During domestic layovers, you are free to leave the airport. If your domestic layover is longer than one hour, you should expect to receive two boarding permits. If you want to check out local points of interest, make sure you get your second boarding pass and print it out before you leave.

Whether you can leave the airport depends on the length of your layover and your visa status. For domestic flights, you can exit and re-enter freely, but you must allow enough time (usually at least 4–6 hours) to clear security again before your next flight. For international flights, you must pass through Immigration and Customs, which means you need a valid passport and any required entry or transit visas for that country. If your layover is less than 5 hours, it is generally not worth the risk of missing your flight due to lines or traffic. However, for layovers of 8+ hours, many travelers explore the city. Some major hubs like Singapore Changi or Doha Hamad even offer free city tours for transit passengers. Always remember that you will be treated as a "new passenger" when returning, so you must clear the full security screening again before heading to your gate.

Whether you can leave the airport during a layover depends on several factors:

1. Visa Requirements

• If your layover is in a different country, check if you need a visa to exit the airport. Some countries offer transit visas or allow visa-free entry for short stays (e.g., 24-72 hours).
• Example: Dubai (UAE) offers a 96-hour transit visa, while Singapore allows Visa-Free Transit Facility (VFTF) for eligible travelers.

2. Layover Duration

• Short layovers (<4 hours): Not advisable due to immigration, security, and potential delays.
• Long layovers (6+ hours): More feasible if immigration is quick (e.g., Istanbul, Doha, or Incheon airports).

3. Airport Location & Transport

• Some airports are far from the city (e.g., Paris CDG is ~30 min by train, while Narita Tokyo is ~1 hour).
• Check public transport/taxi availability and costs.

4. Airline & Luggage Policies

• If your luggage is checked through to your final destination, you won’t need to collect it.
• If not, you’ll need to recheck bags after returning (allow extra time).

5. COVID-19/Entry Restrictions

• Some countries may still require tests/vaccination proof for entry.

Best Airports for Layover Exploration

• Singapore (Changi): Free city tours for layovers >5.5 hours.
• Seoul (Incheon): Free transit tours for layovers >6 hours.
• Istanbul (IST): Easy metro access to the city center.
