The two flights I find AZ has into BOS are:

AZ 0614 Rome-Boston

AZ 0618 Milan-Boston

I don't know which one it is. I don't see anything irregular with the arrival status on either flight at AZ's website. However, Faux News at 11:30am Eastern Time announced an AZ flight bound for Boston was being diverted to Bangor.

No further information was available, but I strongly suspect it has something to do with "lists". Hopefully it won't be another innocent family -- at the same time if it is someone on a list, why don't they just let it goto BOS and grab him/her there? If the destination is BOS, the money spent to divert a flight to BGR has to be substantial.

Hopefully it's not a different/serious matter, as it wasn't stated why the diversion was being done.

Also - if one looks at a great circle mapper, it can also be argued under a great circle routing, BOS would be the first US city flights on the great circle path would arrive at -- but mileage is slightly shorter to BGR.

OT: What about flights which use the southern north Atlantic crossing? There are two common ETOP crossings, one a nothern route which uses Iceland, Greenland, & Canadian cities as potential landing spots.

The second a more southern route which uses the Azores as potential landing spots and then the next possible landing spot would be along the Canadian coastline -- but this flight path often does not overfly Canada. Flights from Spain and Portugal to the east coast often use this southern route. i.e. when I fly MAD-JFK the flight path uses the southern N Atlantic crossing.
