I don't really think MHT
has any "odd" flights, as pretty much every flight from MHT
goes to a major operation for that airline. The closest I can see as odd is Southwest's service to BNA
, as both have daily 737s (BNA
has 2), while BOS
has no service to either city (Eagle dropped BNA
). However, WN
does have the opportunity to connect pax through both cities.
As for BOS
, the only one I can think of is KEF
...it makes sense for connections, and Icelandair does do advertising in Boston to promote tourism to Iceland, but KEF
is certainly not the first place you think of...
