Self-Transfer & Split-Ticket Connection Risk Evaluator

Why Separate PNRs Trigger Strict Onward Ticket Checks at Leg 1

• When you fly Airline A from London to Bangkok on PNR #1, and Airline B from Bangkok to Sydney on PNR #2, Airline A only sees you flying one-way to Thailand.
• Timatic immediately prompts the London check-in agent to verify your right to enter Thailand—including proof of onward travel out of Thailand and visa eligibility.
• Even if you never plan to leave the terminal, low-cost carriers without interline agreements cannot check you through airside, forcing you to legally enter the transit country.

Hidden-City (Skiplagging) Rules & Automatic Return Cancellation

• If you buy New York → Frankfurt → Warsaw because it is cheaper than New York → Frankfurt, the airline checks your documents for Poland/Schengen, not just Germany.
• If the flight is overbooked or suffers an IRROPS delay, the airline has the contractual right to re-route you New York → Munich → Warsaw, completely bypassing Frankfurt.
• Checked bags will always go to the final ticketed city (Warsaw), and gate agents in full boarding groups frequently force-check roller bags at the jetbridge.

Does travel insurance cover a missed flight on a separate-PNR self-transfer?

Most standard credit card and retail travel insurance policies exclude self-transfer misconnections unless the two flights were booked on a single ticket OR you scheduled at least 4 to 6 hours between flights and the first flight was delayed by a covered peril (like severe weather).

Why did the check-in agent demand a visa for my transit country when I have a connecting flight?

On separate PNRs, the first airline has no legal guarantee you will board the second airline—or if your bag is checked, you must physically pass through passport control to collect it. Therefore, IATA Timatic rules require you to satisfy full entry requirements (visa + onward proof) for the intermediate country.

Can airlines ban me or claw back frequent flyer miles for hidden-city ticketing?

Yes. Lufthansa, United, and American Airlines include explicit prohibitions against hidden-city ticketing in their Conditions of Carriage. Never attach your frequent flyer number to a skiplagged booking, and only use it sparingly on one-way, carry-on-only itineraries.

What if I use a hidden-city ticket where the final leg is in a country requiring a visa I do not hold?

You will be denied boarding at your origin airport. Check-in agents verify visas and onward tickets for the final destination printed on the PNR, regardless of your intention to walk out at the layover airport.
