With separate tickets, the second airline may have no obligation to protect you if the first flight is late. That means the connection buffer becomes your responsibility.
Baggage is the first question
Find out whether bags can be checked through. If not, plan for immigration where required, baggage reclaim, landside movement, check-in/bag drop and security.
Airport layout matters
A 90-minute connection at a compact single-terminal airport is not equivalent to 90 minutes at a multi-terminal hub. Check the exact arrival and departure areas before buying the itinerary.
Entry requirements can matter even if you never planned to visit the country
Some self-transfers require going landside. Verify transit/entry rules for your nationality and itinerary with the relevant authorities.
Set a personal minimum
Build a margin that reflects the airport, baggage, immigration, terminal transfer and the financial consequence of missing the second ticket. Cheap itineraries stop being cheap if the recovery risk is high.
Frequently asked questions
Are separate tickets protected if the first flight is late?
Usually not in the same way as a through-ticket. Check the booking terms and airlines.
Do I always need to collect my bags?
Not always, but you should never assume through-checking on separate tickets. Ask the airline.
Why does terminal layout matter?
Because landside transfers, walking and repeated security can consume a large part of the connection window.
Sources and verification
