Tariffs are causing Alaska Airlines to cancel flights. Here's why.

Alaska Airlines is canceling more than a dozen flights a day as tariffs hinder its ability to accept delivery of new aircraft, according to the carrier.

The Seattle, Washington-based airline said it wouldn't immediately accept delivery of two Embraer 175 regional jets in order to avoid incurring the extra tariff-related costs. The aircraft were meant to serve Horizon Air, a regional subsidiary of Alaska Airlines. 

President Trump's tariff agenda has upended supply chains for a range of businesses, and has forced many companies to raise prices on consumers in order to protect their margins. The aviation industry has also warned that the levies will affect its business.
