Hi zai_ruzaini,
Coming back to you on your questions relating to Section 26 (Travel Misconnection).
Regarding your first 2 questions, you are eligible to claim under Section 26 (Travel Misconnection) if you miss your onward travel connection at the transfer point due to overbooking or the late arrival of your incoming flight, and if no onward transportation is available to you within 6 consecutive hours of your arrival.
If you have the option of boarding the connecting flight (as in your third question), you will not be eligible to claim under Section 26 (Travel Misconnection).
However, if you do board the connecting flight, you are covered under Section 29 (Delayed Baggage) if your luggage does not arrive within 6 hours of your arrival at your destination.
You might also be wondering about the documents you would need to submit for a claim under the Travel Misconnection, or Delayed Baggage sections. Do note that you would have to submit a written verification from the carrier, operator or handling agent stating the reasons and length of delay, on top of your basic documents (claim form, travelling schedule, airline ticket, boarding pass and copy of your passport with stamp showing the date of departure and return to Singapore).
We hope that this has helped to clarify!
