Work is due to be completed by the end of 2024, two years ahead of schedule thanks to an accelerated construction timeline achieved during the downturn resulting from the Covid-19 pandemic.
Delta is the largest carrier at LaGuardia, with up to 255 daily flights to around 70 destinations being served this summer.
Commenting on the unveiling Port Authority executive director Rick Cotton said:
“In a word, the new Terminal C is magnificent – an architectural gem that dwarfs the facilities it replaces in size, style and functionality.
“It represents 21st century air travel that is world class in every respect – which can now be said of the entire whole new LaGuardia airport, which six years ago was among the most reviled in the nation.”
