Direct flights from Lisbon Humberto Delgado Airport (LIS) to O'Hare International Airport (ORD) minimize total travel time, lower the risk of missed connections, and simplify baggage handling — making them preferable in January when Chicago winter storms can complicate itineraries. However, nonstop fares can be more expensive; one-stop itineraries via major European hubs can save money but increase exposure to delays and longer total travel time. If choosing connections, allow extra layover time, book through a single carrier for protected connections, and avoid very short minimum connection times during January.
TAP Air Portugal often offers competitive nonstop service between Lisbon Humberto Delgado Airport (LIS) and O'Hare International Airport (ORD) with Portuguese hospitality and a decent baggage allowance on main fare classes, making it a strong choice for direct January travel. United Airlines provides strong connectivity within the U.S., potentially better for onward domestic connections but may offer fewer nonstop Lisbon options depending on the year. Lufthansa and British Airways typically provide reliable one-stop connections via Frankfurt or London with robust lounge access and frequent flyer benefits, though total travel time is longer. For January travel, prioritize carriers with nonstop schedules for reliability, or choose single-carrier connections to reduce rebooking risk during winter disruptions.
Pack layered clothing for your Lisbon Humberto Delgado Airport (LIS) departure and Chicago O'Hare International Airport (ORD) arrival — include a warm coat, insulated footwear, and travel-sized de-icer items if needed.

Finally, sign up for airline notifications and have backup accommodation plans if extended delays occur.
