5 out of their 12 US destinations will get it. New York - JFK, Houston, Los Angeles, San Francisco and Washington - Dulles will see it. Boston, Chicago, Dallas/Ft. Worth, Orlando, Newark, Miami and Seattle will not see it. If we expand to all of their North American service, 6 out of 14 destinations will get it. Toronto will (although Canadian rules only allow for them to serve Toronto a max of 5 times per week). Mexico City will not see it.
As an aside, it's pretty crazy that London is going to see 9 daily A380 flights by Emirates. The amount of traffic is insane.
