From the Urbanomics blog:
"The consortium hired to reconstruct and operate a new terminal at LaGuardia for 35 years secured $2.5 bn of financing through a municipal bond offering which attracted considerable interest. The Baa3 rated (one notch above junk) 30-year 2046 bond was priced with a yield of 3.27% and a 5% coupon. A Bank of America Merrill Lynch index of triple-B-rated munis across multiple maturity dates yielded 2.88%. This is against 2.6% yield for 30 year US Treasuries. The consortium, LaGuardia Gateway Partners, includes airport operator Vantage Airport Group, construction company Skanska, and Meridiam Infrastructure, an investor and asset manager of infrastructure projects."
