In Scotland, there is no terminal 13 in any airport, instead there is a terminal 12B.
Some aeroplanes skip a row 13, going straight from 12 to 14.
Some tall buildings have resorted to skipping the "thirteenth floor", either by numbering it "14" or as "12a".
Some streets do not contain a house number 13.
On the 13th day of the Persian new year (Norouz), people consider staying at home unlucky, and go outside for a picnic in order to ward off the bad luck.
Most race car drivers consider 13 a very unlucky number, as a car carrying that number has never won the Indianapolis 500 or a NASCAR Nextel Cup race, and almost all Formula 1 teams are no longer given the number 13 when car numbers are given out to teams on basis of points. Usually the team finishing seventh in the previous year's championship will take numbers 14 and 15, instead of 13 and 14. Only once in recent years (1991, Ricky Johnson) has an AMA Motocross rider chosen #13 instead of #14. Some NASCAR tracks refuse to have a pit stall #13.
On the Universal Studios sound stages in California, there isn't a sound stage numbered 13.
