Steps
Identify that the itinerary contains two or more separately ticketed flights not protected by a single interline agreement, and surface this clearly to the user before purchase
Calculate the minimum connection time at the self-transfer airport, accounting for terminal changes, immigration/customs requirements for international connections, and checked baggage re-check procedures
Evaluate whether a disruption protection product is available (some aggregators offer a self-transfer guarantee or disruption rebooking product) and, if so, add it to the cart for the user's consideration
At booking, ensure each ticket is purchased with a credit card that offers trip interruption or missed connection coverage, and document this for the user
After booking, monitor the first flight's status and trigger an alert if a delay or cancellation puts the connection at risk, giving the user maximum time to act independently
Known gotchas
If the first flight is delayed and the passenger misses the second flight, the second carrier has no obligation to rebook at no cost — the passenger must purchase a new ticket or invoke trip protection
Baggage is not automatically transferred on virtual interline itineraries; the passenger must collect and re-check bags at the connection point, which can be impossible in short connection windows
Some aggregators market virtual interline products as 'protected' connections with vague SLAs — read the exact protection terms before relying on them in automated rebooking logic
