In the Southeast Asian country of India, exhausts from old cars and motorcycles, pollutions from industries, dust smoke from cooking and fires from when farmers burn their crops double, all of this contributes to the toxic air pollution in the Indian capital of New Delhi. More than 25 million people live there and many of them are suffering with air conditions that one doctor compared to smoking 50 cigarettes a day.

Now, United Airlines has suspended its flights to the city because of what it called poor air quality concerns. At least through Monday, no United flights are landing in, taking off from or connecting in India's capital. The company is treating conditions there like it treats severe weather or other events like a volcanic eruption. For those with flight tickets, United is offering travel waivers, to allow passengers to choose another flight without paying for the change.

New Delhi is under a public health emergency, schools have been closed, tracks from other areas are not allowed to enter the capital, construction projects have been put on hold. Pollution is not something that's new for the city. It's a part of life there, especially this time of year. But that doesn't mean that residents can get used to it, or avoid suffering from it.
