A return ticket yyz to bgi (Bardados)same dates as above via MIA on AA is $932 and in reverse $1010 but Barbados is almost twice as far from MIA as Belize is. MIA to BGI 1606 miles MIA to BZE 877 miles
But with more demand (volume) wouldn't that allow them to increase not decrease the fare? I think the same airlines service Barbados and Belize except Continental. If they were concerned with the cost of each plane load wouldn't they save money using bigger planes?
