James,
The trouble is, that there are about 3000 cities in the text file. I'm

Assuming the first field (i.e. CYGL) is unique, just read each line and
check using a regular expression whether it matches the city you
require. If it matches, you can stop reading the file and do whatever you
need to do with the line.
