Flew DL 138 and DL139 in the past 3 weeks. Both flights (J) were front to back. Seems some consistency is missing.
On the positive side, the priority baggage tags do appear to be working. We make it from the plane, through immigration, baggage claim and customs in 30 minutes (ATL) on Sunday. Used to be baggage claim was the one thing which caused us to miss connections in the past.
