US Airways
PHL - DUB was 5 weekly 767 this year and 2 weekly 757 until CLT started/finished when it was daily 767.
DUB and GLA were released as 757 next summer becasue PHL - FRA drops from A330-200/300 to a 767 except for the peak months of June - Sep. So would expect a 767 to appear at some stage.
