This morning, United confirmed that the "9/11 security fee" will not be collected on tickets issued for flights during the period June 1 through September 30, 2003. Procedures should be in place later today. (This is good for me, because tomorrow I have to ticket three award itineraries for flights in July.)
United did not know yet whether travelers with tickets already issued for flights during that period can get the fee refunded. (I have two of those.) I assume the answer will be yes.
