The studies

Study #1 — Airline booking windows vs organiser decision windows

Delta's 240-day and 331-day regional windows, American Airlines' published group terms including minimums and adult-to-minor ratios, and the distinction between when a file can open and when an organiser should start.

Airline open windows are not the same as organiser decision windows.

Study #2 — Group fare vs DIY tickets, an 8-factor matrix

Eight programme factors scored GROUP, DIY or DEPENDS, plus the decision rule and a six-layer cost comparison.

Four or more GROUP signals favour opening an airline group file; four or more DIY signals favour public tickets; a mixed score means quote both.

Study #3 — School trip booking calendarIn production

Will map term planning and consent timelines against airline open windows.
