Probably need to include new One WTC tower.
Also, Newark Liberty airport is located in NJ, not in NYC.
Should the question read, airports servicing NYC?
You didn't include the Frick Collection on Museum Mile.
You said largest TRADING companies in New York. This is misleading since Verizon and Pfizer aren't TRADING companies, they're TRADED companies.
4th, 7th, 9th and 10th Avenues are not "alternately known" as the names you put down, they eventually become those avenues.
And I'm with NCsupercade - first of all, only tourists EVER refer to 6th Avenue as "Avenue of the Americas". 7th, 9th and 10th as stated become those streets on the Upper West Side.
8th Avenue has become Frederick Douglas Boulevard
