  "connection_tips": "Connecting through Chicago O'Hare International Airport (ORD) requires careful planning, particularly when transferring between the main domestic terminals (Terminals 1, 2, and 3) and the primarily international Terminal 5. After re-checking your bags, take the ATS to your domestic departure terminal and clear TSA security there.\n\nA highly efficient alternative for passengers on a single ticket who do not need to collect their luggage is the Terminal Transfer Bus (TTB). If the TTB is not running, or if you are on separate tickets, you must use the landside ATS and re-clear security at your next terminal. O'Hare is a place where terminal choice and connection timing matter, because the airport is large enough that the wrong assumption can cost real minutes. A minimum connection time of at least three hours is strongly recommended for international-to-domestic transfers to account for potential CBP delays and terminal changes.\n\nUnlike the domestic terminals, Terminal 5 is physically separate and is connected to the rest of the airport via the 24/7 automated Airport Transit System (ATS). This airside shuttle operates daily between approximately 11:30 AM and 9:30 PM, allowing you to move between terminals without exiting the secure area or re-clearing security. Utilizing the Mobile Passport Control (MPC) app can help expedite the immigration process.\n\nFor most international arrivals, you must clear immigration and customs at Terminal 5, collect all checked baggage, and then re-check your bags at the dedicated airline counters located just past the customs exit. The TTB can be accessed from Gate M13 in Terminal 5, Gate C18B in Terminal 1, and Gates G17 or K20 in Terminal 3. Travelers should also note that some domestic carriers, such as Delta and JetBlue, now operate out of Terminal 5, so it is essential to verify your departure gate on the information screens before heading to the main terminal core.",

  "terminal_info": "O\u2019Hare International Airport has four terminals: Terminals 1, 2, and 3 form a horseshoe connected by airside walkways, while Terminal 5 handles most international flights and sits across the airfield. The Airport Transit System (ATS) train links all terminals, parking, and the rental car center on a frequent loop.\n\nWalking between concourses inside the domestic complex is straightforward\u2014Concourses B and C in Terminal 1 are joined by the underground neon tunnel (5\u20137 minutes end to end), Terminal 1 to Terminal 2 takes about 8\u201310 minutes, and Terminal 3\u2019s farthest gates are 12\u201315 minutes from Terminal 1 via secure corridors. Travel to Terminal 5 requires exiting or riding the ATS from the domestic terminals; the train ride is about 8 minutes with another few minutes of platform access.\n\nEach terminal hosts multiple TSA checkpoints with PreCheck and CLEAR lanes; the main checkpoints in Terminals 1 and 3 open earliest for banked morning departures. Typical waits run 15\u201325 minutes, but peaks before 7 a.m. or during holiday afternoons can exceed 35 minutes, so the TSA \u201cMyTSA\u201d feed is useful for live estimates. Re-entry from Terminal 5 to domestic gates requires clearing security again.\n\nImmigration and customs for most international arrivals are handled in Terminal 5\u2019s expansive arrivals hall with Global Entry, Mobile Passport, and baggage re-check desks for onward connections. Certain precleared arrivals from Canada and select international flights on United or American may use facilities in Terminals 1 or 3, but transfer passengers should follow airline-specific signs before boarding the ATS.\n\nAmenities are extensive: United Polaris and United Club lounges populate Terminal 1, Delta Sky Club sits in Terminal 2, and American\u2019s Admirals Clubs and Flagship Lounge anchor Terminal 3. Terminal 5 offers lounges for Delta, Air France/KLM, British Airways, and others, plus a large dining court. Nursing rooms are available in every terminal, \u201cKids on the Fly\u201d play areas sit near Gates F1 and in Terminal 2\u2019s rotunda, and all concourses provide elevators, moving walkways, and adult-changing stations for accessibility.",
