US Airways Moves To D-Gates in Las Vegas
Starting tomorrow we will begin service out of the D gates at Las Vegas McCarran International Airport (LAS) instead of the A gates we currently utilize. We will now be operating out of gates D1, D3, D5, D7, D9 and D14. This move is to benefit our passengers with a more modern and seamless experience. As a result of the move, we are requesting that our customers now check-in 45 minutes prior to departure vs. the 30 minutes we required prior to the move. We now share the concourse with American Airlines and the terminal with Delta, United, Allegiant and Hawaiian. Our ticket counter and baggage claim will remain in the same area, which is in Terminal 1.
