United Airlines will reach more destinations in Mexico thanks to a deepened commercial partnership with Aeromar, Mexico’s executive airline, which will also increase flights significantly. The six-year-old partnership will continue to bring benefits for both airlines. Their websites have already been updated with the new routes, making it easier for customers to plan their trip, and they’ll be able to know which flights are United Airlines and which are Aeromar. This code sharing agreement includes “Through Check-In”. Using only one purchase code and going through just one baggage check, passengers do not need to repeat the process at layovers.
