Separate tickets: what non-revs need to know at a connection

Can you connect between two airlines on separate tickets? Yes. But it works differently from a trip on one ticket. When you hold one ticket for the first flight and another for the second, the two airlines treat you as two separate passengers. Nobody is responsible for getting you from one to the other except you.

This guide covers what changes: protection, bags, immigration, documents, and how much time to leave.

A staff travel agreement is not an interline ticket

"Interline" means two different things in this industry, and the confusion causes real trouble at connections.

• A ticketing interline is an agreement that lets two airlines put flights on one ticket and pass your bags between them. Paying passengers who book a trip with one ticket across two airlines benefit from it.
• A staff travel agreement, such as ZED, lets you fly another airline at a staff rate. It gives you a ticket on that airline. It does not join that ticket to the one you hold on your own airline. (New to ZED? Start with What is ZED travel?)

So two staff tickets on two airlines are normally two unrelated tickets, unless your employer tells you otherwise. The industry calls this self-connecting, or a self-transfer.

What "protected" means, and why you usually aren't

A protected connection is one where the airline is responsible for getting you to your destination if the first flight is late or cancelled. On one ticket, if you miss the second flight because of the first, the airline rebooks you.

On separate tickets, the second airline has no link to the first. If your first flight arrives late and you miss the second, you are a no-show for that flight. Airlines' conditions of carriage set out their responsibility for connections. As one example, Cayman Airways' published conditions of contract say it is not responsible for "failure to make connections" (Cayman Airways, as of October 7, 2026). Check the conditions of each airline on your trip.

For a non-rev, there is a second layer. On standby, you were never confirmed on either flight. If you miss the second, you list again for a later one, subject to space and the operating airline's rules.

Bags: plan to collect and recheck

On separate tickets, assume your checked bag stops at the end of each ticket. Heathrow says it plainly: if you have booked two separate flights, "you're not technically a connecting passenger", and you will need to pass immigration, collect your baggage, then check in, drop your bag and go through security again (Heathrow, as of October 7, 2026). Gatwick tells travelers whose bags are not checked through to ask their airline for its own minimum connection time (Gatwick, as of October 7, 2026).

This is a good reason to travel with carry-on only when you can:

• You skip the wait at baggage reclaim and the second bag drop.
• You don't risk a bag flying on a flight you didn't get on.
• If you have to change plans, your things are with you.

Our packing guide for standby days covers what fits in one bag. If you must check a bag, check each airline's bag drop cutoff for the second flight, not only its boarding time.

Immigration at the connection

When you collect bags and check in again, you leave the airport's international transfer area. Heathrow, for example, says separate-ticket travelers pass immigration. That means entering the connecting country, even if you only stay for two hours.

That changes the documents you need. A few examples, as of October 7, 2026:

• United States. U.S. Customs and Border Protection states that Visa Waiver Program travelers "require either an ESTA or a visa to transit the United States" (CBP). Plan any US connection as an entry, with the documents that requires.
• Canada. Canada requires an eTA to transit by air for travelers from eTA-required countries, and a visa for visa-required travelers. US citizens and US lawful permanent residents can transit without a visa (Government of Canada).
• United Kingdom. You need an Electronic Travel Authorisation (ETA) if you pass through border control at a UK airport before continuing your journey. An ETA costs £20. There is an exemption when you transit airside without passing through border control, and GOV.UK advises checking with your airline if you are not sure (GOV.UK, when you do not need an ETA; ETA overview). If you have to collect a bag and check in again, you pass through border control, so the exemption won't help.
• Schengen area. The EU's Entry/Exit System (EES), which registers non-EU travelers at the external border, became fully operational on April 10, 2026 (European Commission). If you enter the Schengen area at your connecting airport, that is where registration happens, not at your final destination.

These rules depend on your passport, and every traveler in your group may need something different. A spouse with another nationality, or a child on a different passport, can need a document you don't.

Verify before you fly: check the official government page for every country where you connect, for every passport in your group, in the week you travel. The links above are where to start. Rules change, and some change with little notice.

Connection time: set your own

You will see the term MCT, minimum connecting time. IATA defines it as the airport's official shortest time to transfer a passenger and their luggage from one flight to a connecting flight (IATA).

MCT is built for protected connections, where your bag is transferred for you. It does not include the time to clear immigration, wait for a bag, check in again and clear security. Heathrow says its minimum connection times don't apply to separate bookings. Gatwick, for its own airport, advises separate-ticket travelers to allow at least 60 minutes in the same terminal and at least 90 minutes between terminals, and notes that airlines may require more. Those are one airport's figures, not a rule for others.

When you build a self-connection, add up the steps yourself:

1. Time to leave the aircraft and reach immigration.
2. Immigration, which varies by time of day and passport.
3. Baggage reclaim, if you checked a bag.
4. Getting to the second airline's check-in, possibly in another terminal.
5. The second airline's check-in or bag drop cutoff.
6. Security, then the walk to the gate.
7. On standby, time to see the gate agent before the flight.

Then add a margin for a late first flight. How big that margin should be is your call. It depends on the airport, the time of day and how many later flights you could fall back on.

Terminal changes

Many large airports have more than one terminal, and your two airlines may not share one. Check the airport's official transfer page for how you move between terminals and how long it usually takes. Allow extra time when the second terminal is landside, outside security.

What to check for your trip

• Each airline's check-in and bag drop cutoff for the second flight.
• Each airline's bag rules for staff travelers.
• The entry and transit rules of every country you connect in, for every passport in your group.
• Each operating airline's rules for staff travelers, including listing and dress code.
• The next flights you could fall back on if you miss the connection.

What this means for you

1. Treat every airline change as two trips, with no one responsible for the gap between them except you.
2. Travel with carry-on only when you can, so you don't depend on a bag transfer that isn't there.
3. Check entry rules at each stop for every passport, on the official government page, the week you fly.
4. Set your own connection time from the steps above, not from the published MCT.
5. Know your fallback flights before you leave, on both airlines.

Planning a multi-airline trip like this is what we are building for. InterlineConnect is a planning tool for non-rev travelers, in private beta on iPhone. Early access opens soon.

Rules differ by airline and change. Your employer's staff travel policy always wins.
