Case Study: Aer Lingus achieves significant cost savings in 2 days with Tableau Software

2 days to significant cost savings at Aer Lingus

Aer Lingus, Ireland’s flag carrier, needed to drive down cost per seat by better connecting daily planning, crew rostering and maintenance activity. Production Planning Manager Jonathan Capper had been working from a massive, 50 MB spreadsheet with over a million formulas that took weeks to understand and couldn’t easily reveal the true drivers of engine and operational costs.

By adopting Tableau he built interactive dashboards and a 60‑page workbook that let him explore trends in minutes instead of weeks. Within two days he uncovered previously hidden engine‑cost issues, reworked instructions, and rolled out changes that produced significant dollar‑amount savings — turning a slow, error‑prone process into a fast, insight‑driven workflow.
