Quick Read:

Within air travel, a SOTO ticket means Sold Outside, Ticketed Outside – ie. an airline ticket that has been bought and issued from a country that doesn’t feature in the travel itinerary.

For example, if a UK traveller buys their ticket in the UK but they’re travelling from New York to Los Angeles, that will be a SOTO ticket. With regards to the location of these operations relative to the origin of the traveller, tickets may also be SITI, SITO or SOTI, specifying inside or outside.
