With eight hubs across the United States (including Guam), the Chicago-based carrier offers an expansive and ever-growing network of international destinations. Recent additions include Amman, Jordan; Bergen, Norway; Johannesburg; Lagos, Nigeria; Accra, Ghana; and a trio of island hotspots that have historically been tricky to get to from the U.S.: the Azores, Mallorca, and the Canary Islands. The airline responded to the pandemic by eliminating change fees for most flights, and it will soon welcome 270 new Boeing and Airbus planes to its fleet. The new aircraft will of course make your flight more comfortable and high-tech, but they come with an added bonus: They’re expected to reduce carbon emissions by 17 to 20 percent per seat, compared to older planes.
