All tickets which do not have even 1 confirmed or RAC gets cancelled automatically and you get a refund in your account (the means by which you had paid for the ticket). If you have even 1 RAC or Confirmed ticket in your PNR the entire ticket is valid and you can travel.

If a single ticket within a multi-passenger Passenger Name Record (PNR) is not confirmed, that specific traveler will likely be denied boarding at the gate. A PNR can exist even if the underlying ticket has not been "issued" or "synced" with the payment. This often happens due to payment processing delays, a mismatch between the airline and a third-party booking site, or technical glitches during a schedule change. The "gold-standard" for passengers in this situation is to check for an e-ticket number (a 13-digit code starting with the airline's specific prefix) for every traveler. If one person has a PNR but no ticket number, their seat is essentially just a "reservation" without a valid contract for carriage. In 2026, airlines have improved automated re-syncing, but you should still use the "Manage Booking" tool to verify the status of each passenger individually. If a ticket shows "Pending," you must contact the airline immediately to resolve the issue before heading to the airport to avoid being separated from your traveling party.
