Dulles lounges stay put as $19.9B overhaul advances into mid‑2030s

Washington Dulles’ $19.9 billion redevelopment was approved by MWAA, ensuring the long‑running mobile lounges (and the related AeroTrain) will remain in operation through the mid‑2030s while a connector to Concourse A‑B is built and major expansion work—including United’s Concourse E and a new United Club—gets underway; the plan unfolds over several years with Concourse E‑F completing by the early 2030s and later phases postponed into the late 2030s.
