In admin:
class Trip(...):
....
class Admin:
js = ['/your/js/to/do/filter.js/']
http://www.djangoproject.com/documentation/model_api/#js
But if not for admin, you can do a similarly unobtrusive thing. The
select element for the company will have an ID. Hook the change event
on it and re-fill the aircraft select elm using the json results of a
xmlhttprequest to a custom view.
Check out django.core.serializers:

If that warning scares you, check out django.utils.simplejson instead. :)
