I always just think its funny they're just dumping more pollution on their own country (longer APU times longer flights etc etc) and in making more work for themselves to allow Mr Iberia land before any low-cost guys or not saying anything when some aircraft slows down very early to try and make other low-cost guys have to do go-arounds.
If your angry and want to do a go-slow, fine fire away but at least do them properly eh?
