Travel planning
Decide whether a stopover leaves time to go into town
A long connection does not automatically mean a useful city visit. Start by finding the time you must be back at the airport and the rules for leaving it.
What to check in the reply
Use official government and airport sources for entry requirements, security and transport details. The assistant should leave an uncertain immigration requirement unresolved rather than assuring you it will be fine. Account for getting off the plane, storing bags if needed, both transport legs and returning for the next flight. Check whether the next departure uses a different airport or terminal.
The next step
Make the final decision after seeing the inbound flight's actual arrival and current airport conditions. Keep the outing optional and avoid a booking you cannot cancel. If any requirement remains uncertain, ask the airline or relevant authority. Save the airport alternative so a delay does not leave you without a plan.
