Special Deals Via Email Alerts
If you travel frequently, you may wish to consider signing up for email alerts. These are sent by many airlines when they are having web-based specials. I have had a few very cheap airfares by having been alerted in this way.
If you use one hotel brand or go to the one destination frequently, you could even see if that hotel brand also email alerts for specials and promotions.
On the other hand, these will be more emails to clog up the inbox: depends on your preferences.
