A little over a year ago American Airlines started offering more coach award space, and they did it in an interesting way. They started opening up award space on a married-segment basis — availability wasn’t for a specific flight but for an entire itinerary.
Agents are now being reprimanded for helping customers to work around these restrictions. And married segments make it very difficult to make changes to an award later, a real blow to Executive Platinums and ConciergeKey members who have free changes as a program benefit.
