The main North American airlines are already warning passengers about the possibility of flight cancellations and postponements throughout next week.
Tens of millions of Americans are suffering the effects of a massive winter storm that could bring the coldest temperatures in a decade. The Central states are the most affected, but the bad weather conditions are expected to extend across the entire East of the country.
Several regions have declared a state of emergency and civil protection services are advising people to stay at home whenever possible.
Forecasters say this could be the worst winter storm this decade, with record snowfall and freezing temperatures.
It started in the Central United States, but is spreading to the East of the country and, predictably, tens of millions of Americans will be affected in the coming days.

The storm is being caused by a polar front coming from the Arctic and experts say it could make this the coldest January in the last 15 years.
Several roads and highways are already closed. Authorities have already warned that conditions will worsen and that many others will have to be closed because road traffic will become very dangerous.
The main North American airlines are also alerting passengers to the possibility of flight cancellations and postponements throughout next week.
Some airports have already closed and, in many places, there are no longer train or boat connections.
More than 60 million people live in the regions hardest hit by this storm.
