RAT5 has a point in that some route announcements can be pretty dull - especially those that join the dots or are between bases. An example might be a Warsaw Modlin - Ibiza summer seasonal route; new information but hardly groundbreaking.
Other new routes are rather more interesting for a variety of possible reasons, perhaps because it involves adding a new airport to the network, a change of strategy or indicates a desire to have a price war with a rival.
Very difficult to know which routes are dull and which are interesting.
