Is It Possible for Checked Bags to Arrive Without Issue? The luggage and seat service on my most recent United Airlines CDG Terminal were better than I had anticipated. The United app made it easy to tag and track my bag, and check-in was swift. For extra legroom, I chose an Economy Plus seat, which enhanced my overall comfort throughout the long flight. Overall, the journey was smooth and traveler-friendly from start to finish, and the staff was helpful with my big carry-on.
