Travelport told its travel agency subscribers that it is on the verge of terminating its full-content agreement with Frontier Airlines due to a change in the carrier’s distribution policy.

The carrier is seeking to drive more traffic to its website by making other booking options less attractive.

For example, only bookings made on flyfrontier.com are eligible for advance seat assignment. And, bookings made on the site earn 100% of miles flown; others earn 50%.
