If part of your services include booking local flights, sightseeing flights, bus tickets or train tickets for guests, you may find it useful to have the airports/stations you use on a quick reference list. You can edit and add more codes as needed.

This can also be a handy reference if you provide transfers for guests. whether you use in-house drivers and vehicles or you contract with taxis or other outside operators, it may be useful to list airport or station codes for quick picking from drop-down lists.
