Amazon is adding 4 jets to join Amazon Air fleet

The expansion comes as Amazon continues to push for faster delivery amid a pandemic-fueled surge in online orders. Stuck-at-home shoppers have turned to the service for both essential and nonessential goods, while the holiday shopping season generated further demand for speedy delivery. The four WestJet planes are being converted to cargo jets and will join the Amazon Air fleet this year, while the seven Delta planes will be added in 2022 after their conversion, Amazon said.
