Cirium: Radical Shifts in US Flight Schedules This Summer Reveal Why Airlines Need New Planning Tools to Stay Ahead of the Curve

At the start of May 2021, the plan for what carriers would fly in September was more or less in line with pre-pandemic levels in 2019. By the time they came to fly the September schedule, American Airlines, Delta Air Lines, Southwest and United Airlines had significantly cut back their flights.
Airlines are now making major changes to the way they schedule flights—publishing or removing them much closer to the date of departure as they struggle with the uncertainties brought on by the pandemic.
Prior to the pandemic schedules would remain fairly stable over a season, with few changes—positive or negative—as the plan was refined.
Only 3% of flights were removed from the September schedule in 2019 compared with the plan published in May that year.
The new Diio Schedule Snapshot web-based tool enables airlines and airports to track changes to the flights being scheduled at different points in time. It provides much more detail on schedule changes than has been done in the past.
“In today's environment where travel restrictions and vaccination programs are significantly impacting flight schedules, airlines have had to adapt and issue changes to their schedules frequently and much closer to the day of departure. The traditional methods used to analyze demand need to be more dynamic,” said Kevin O’Toole, Chief Strategy Officer at Cirium.
“Using Diio Schedules Snapshot, airlines and airports can understand schedule changes over time, optimize future schedules, build stronger models for planning and revenue management, and optimize yield through trend analysis.”
The analysis of the major US airlines evidences the radical shift in the summer flight schedule and the impact that the pandemic has had on the variance in airline planning year-over-year.
Understanding and comparing changes to the published flight schedule over time as it gets closer to actual departure, enables analysts to stay ahead of the curve, and provides new insights for planning and revenue management.
Reviewing historical data by publication date also provides insights on airline and airport strategies in an uncertain world.
Diio Schedule Snapshot is part of the unrivaled Cirium Diio suite of products for airline planning. The suite includes Diio Mi, SRS AnalyserTM, Cirium Scenario Planner, and Diio Traffic and Fares.
The new tool integrates with Cirium Diio Mi or SRS Analyser and is the first of many more new tools in the Cirium pipeline to help airlines optimize their schedules and find new revenue opportunities.

Vycellix Prepares for First-in-Human Study of Novel Allogeneic Cell Therapy Powered by Its Universal Cell Engineering Platform3.12.2025 19:00:00 EET | Press release
Vycellix, Inc., a biotechnology company developing next-generation allogeneic cell therapies designed to overcome the risk of immune rejection, today announced the successful completion of pre-clinical development for its universal cell engineering platform (VY-UC) with rigorous studies across many donor cell types proving robust immune evasion with functional persistence. The Company is now preparing for first-in-human clinical validation by seeking regulatory approval in Sweden to initiate a Phase 1 study for its lead VY-UC product candidate, a novel, off-the-shelf natural killer (NK) cell therapy (VNK-101) for patients with relapsed or refractory multiple myeloma.
