My website - www.flilu.com is a a flight engine that look for flights.
However, in my "From" form there you can't look for specific airports.
For example - www.kayak.com "from" field, you just write TL... and it gives you Tel Aviv airport as an option.
1. How can I include all the airports? Do I need to request a specific API?
2. How does the form auto complete?
