Houston Airport System is embarking on an ambitious project to modernize the George Bush International Airport (IAH) International Terminal and further cement Houston as a global city. The IAH Terminal Redevelopment Program, also known as ITRP, is the largest expansion program in the 53-year history of Bush Airport and builds on a series of previous renovation programs. The program budget is approximately $1.458 billion and is anticipated to be completed in 2025.

ITRP supports the development of additional facilities needed to address aging infrastructure and unprecedented international passenger growth at Bush Airport. The program supports international flight operations for United Airlines and more than a dozen foreign flag carriers. Six new gates will accommodate continued international airline growth and larger, wide-body aircraft.

The program will improve current and future roadway and curbside capacity constraints, expand capacity of the baggage handling system and significantly enhance the overall passenger experience.

The future buildout of the Mickey Leland International Terminal Complex is a mix of new construction and renovated or modified work.
