Airlines and other operators often use “best router” tables in routing, but not always the best routing tables, according to the head of the UK’s aviation regulator.
The Irish Times is reporting that Irish Airways has been using the wrong routing table since it became the first airline to offer direct flights to destinations in the U.K. from the United States.
In addition, the Irish Times says, the company’s own network has been working on its own routing tables for more than a year and hasn’t made any major changes.
The U.S. carrier has been offering direct flights from the U to Dublin since 2016.
It’s unclear why the U-turn occurred, though the Irish Tribune reported that it had been trying to find out for some time.
