“One layover is fine.”
“The second one should be fine too.”
That’s how many travellers think when booking a cheaper multi-stop route.
Two connections.
One final destination.
And one missed rule can stop everything.
Travellers often check the final destination and ignore the transit countries.
But each layover country can have its own rules.
One transit country may treat your route one way.
Another may apply a completely different check.
The airline looks at the full journey before allowing you to board.
The booking can go through.
But that does not mean every rule has been cleared.
Airlines check whether passengers appear eligible to complete the entire journey.
If one transit point creates a problem, the whole trip can fail.
This can happen even when:
With multi-country routes, one missed transit rule can block the entire trip.
Transit rules can change from country to country.
The outcome may depend on:
A route that looks efficient can carry hidden compliance risk.
Multi-stop route issues are hard to fix at the airport.
By the time the airline flags the problem, changing flights may be expensive or impossible.
Before you travel, check every transit country, your passport, and your final destination together.
