Most of the links for airfare deals on Loyalty Traveler are Google Flights links.
None of the links to Google Flights or any other travel booking sites on Loyalty Traveler blog are affiliate links, so there is no incentive for me to steer readers through any specific booking channels like Momondo.com or Priceline.com. All links provided to airline booking sites are for informational purposes only and are not a Loyalty Traveler endorsement for any online travel agency.
Many of these fares are only available 6 to 18 hours, a few fares last several days. Many of these deals appear, go away within a day and are repeated again within days or a week or two later. This is why I do not mark fares “Expired”. A deal from last week may have expired and be back again when you click on the Google Flights fare links.
