What The S/O Or SPTC Symbol On Your Boarding Pass Really Means
By Jenna Busch

VACATIONS

You might notice S/O or SPTC on your boarding pass, but they’re nothing to worry about. S/O means you have a stopover and SPTC means your stopover is longer than a few hours.
SPTC (“Stopover Paid by the Carrier”) might get you a discount on accommodations and other things. Some airlines allow you to take 24 hours to 10 days on a stopover.
Airlines have different policies, but discounts can include hotels, tours, museum admissions, and restaurants. If you want to add a stop, just click “add stopover” when you book.
