Singapore Airlines Web Check-In Not Working? Common Fixes

Web check-in hasn’t opened yet: Check-in opens 48 hours before departure. If you see "check-in not available", you’re simply early — try again once the window opens.
"PNR not found" or check-in restricted: Re-check the PNR (6 characters) and last-name spelling against your ticket. Some international, codeshare, or special-fare bookings can’t be checked in online — in that case use the airport counter.
It won’t proceed without paying for a seat: Pick any free/standard seat to continue — preferred, window, aisle and extra-legroom seats are chargeable, but a standard seat lets you finish check-in at no cost.
Name doesn’t match / spelling error: Minor spelling differences are usually fine. For a real mismatch, contact Singapore Airlines to correct it before travel, or check in at the airport counter with your photo ID.
Boarding pass won’t download: Try a different browser or the Singapore Airlines app, disable any pop-up blocker, or choose "email boarding pass" and print/save the PDF from your inbox.
