Asia-Europe shipping faces a 78% decline in schedule reliability, complicating logistics for freight forwarders amid rising blank sailings.
Freight forwarders active on Europe trades have encountered a consistent operational reality in recent months: vessels listed on the schedule one week may not appear the next, and services advertised as direct may subsequently revert to transhipment.
Sea-Intelligence has quantified this experience in a recently published analysis, measuring schedule reliability through the volatility of weekly service departures and comparing the period from 2020 to 2026 against the pre-pandemic baseline of 2013 to 2019. The findings indicate that weekly departure volatility on the Asia-North Europe trade has expanded by 78%, while the Asia-Mediterranean trade has widened by 71%.
Transpacific trades have recorded deterioration as well, though at comparatively lower magnitudes: the Asia-US West Coast trade has expanded by 48%, and the Asia-US East Coast trade by 26%. No major east-west trade corridor has been spared, but the Asia-Europe trades stand as the most pronounced examples of instability. Sea-Intelligence Chief Executive Officer Alan Murphy has noted that weekly available capacity fluctuates continuously, rendering supply chain planning for cargo owners 'extremely difficult.' The irregular arrival of vessels and container volumes at destination ports directly elevates the probability of sudden congestion events.
Drewry's Container Insight Weekly reports that across weeks 46 through 50 - spanning 9 November to 14 December - 717 sailings are scheduled on the principal east-west trades, of which 46 are projected to be blanked, representing a void sailing rate of 6%. By trade distribution, Asia-Europe trades (North Europe and Mediterranean combined) account for half of all cancelled sailings, with transpacific eastbound accounting for 35% and the transatlantic for the remaining 15%. The concentration of blank sailings on Asia-Europe trades is therefore significant: the trade corridor exhibiting the fastest deterioration over seven years also carries the highest proportion of near-term cancellations.
Schedule instability does not remain contained between carriers and cargo owners; its effects propagate downstream through each link in the logistics chain. Irregular vessel arrivals generate fluctuating terminal workloads, which raise the probability of acute congestion, extend vessel waiting times at berth, suppress on-time performance, and push delays forward into subsequent sailings. Sea-Intelligence's analysis describes precisely this compounding cycle. The operational experience on Europe trades this year has followed the same trajectory: carriers have simultaneously announced rate increases and exercised capacity discipline through blank sailings, resulting in schedule tables that have required weekly revision.
Schedule reliability represents a material operational asset that has been substantively eroded over the past seven years - an erosion that the 78% figure makes concrete and documentable. The assumption that a given trade will reliably offer weekly departures on a fixed day of the week can no longer be treated as a planning baseline. For freight forwarders managing time-sensitive cargo, maintaining contingency arrangements with a minimum of two carriers per trade provides essential operational cover. As the mid-November rate adjustment date approaches, rate levels and vessel schedules will shift simultaneously, making weekly carrier schedule monitoring a more consequential activity than rate table tracking alone.
Looking further ahead, the approaching annual contract negotiation season presents forwarders with a specific and quantifiable basis for contractual commitments on schedule reliability. Embedding the seven-year, 78% volatility record into contract annexures - with defined performance benchmarks and remedies - carries considerably more weight in formal negotiations than qualitative expressions of dissatisfaction at the negotiating table. So long as blank sailings remain carriers' primary instrument for capacity management, that figure is likely to increase further in the year ahead.
