AskWaves explains how the gap between air and ocean freight transport has narrowed during the pandemic. From the report: The air rate from China to the U.S. West Coast during the first week of November was about $14 per kilogram, double what it was a year ago, according to the Freightos Air Index. Shipping by air to the East Coast cost about $13, also twice as much as in 2020. [...] Air is usually the mode of last resort, limited to perishables and high-value goods with margins that can cover the extra expense. Incredibly, airfreight has become a bargain relative to ocean shipping for many companies, especially when measured against the cost of stockouts and lost sales. That's what happens when supply chains are turned upside down by constant chaos. Ocean shipping demand to North America is up more than 20% compared to 2019. Carriers and ports have been overwhelmed, resulting in huge delays and port backlogs demonstrated most clearly by the 80 container vessels waiting last week for a berth at the ports of Los Angeles and Long Beach. Glitches in the system -- from COVID outbreaks to accidents -- created more havoc because the system is so stretched. Spot tariffs -- for immediate transactions not subject to more favorable long-term contracts -- can cost upwards of $20,000 for a forty-foot equivalent unit from China to the West Coast when a host of premiums and surcharges are included. That's 10 times greater than pre-pandemic rates and doesn't even include domestic transportation to move a shipment across the country. Many companies, especially retailers worried about product shortages for big holiday shopping events, are trying to make up for lost time by shifting goods that normally move by ocean to air. The decision to convert ocean freight to air is easier for shippers because air transport is much more cost-competitive than it has ever been. Pre-pandemic, the average price to move air cargo was about 13 to 15 times higher than ocean, but now it is only three to five times more expensive, according to the International Air Transport Association and industry experts.
