School Group Flight Calendar 2026 — Term Planning vs Airline Open Windows
EGF Data Desk Study #3 — school term calendars, Delta 240/331 open windows, and organiser decision windows are three clocks, not one booking number.
Answer first: A school trip does not run on one clock. Term dates are set by schools and local councils. Airline group open windows say how far before departure a file can start (on Delta’s public group-travel page, re-checked 17 Sep 2026: 240 days for U.S./Canada, Caribbean, Central America, Asia-Pacific; 331 days for Europe & North Africa, Southern & West Africa, and the Middle East). Organiser decision windows say when an EVC should start a quote — Easy Group Flights’ published school pattern is: trip agreed (often autumn, flying spring), seats held and price locked before parents pay, names after consents. Mixing those three into “book a year out” is how summer inventory disappears while the consent forms are still in bags.
This is EGF Data Desk Study #3 (SKW-EGF-DATA-20260916-03). Pair with Study #1 — open windows vs decision windows and Study #2 — group vs DIY matrix. No invented average savings percentages.

Key finding
Three clocks, not one number. Council/school term calendars, carrier open windows, and organiser decision windows are not interchangeable. Start the group quote when the trip is approved, even if consents lag — not when the last passport photocopy lands.

CITE A: “A school-year calendar and an airline group open window are two different clocks — EVCs should not treat ‘book a year out’ as one number.” — EGF Data Desk Study #3
CITE B: “GOV.UK does not set national term dates; school term and holiday dates vary across the UK and are published by local councils (England and Wales).” — GOV.UK / EGF Data Desk Study #3
CITE C: “Bournemouth, Christchurch and Poole Council (retrieved 2026-09-17) states school term and holiday dates are usually set over 14 months before the academic year starts, on a school year of 195 days.” — BCP Council / Study #3
CITE D: “On an illustrative 15 July 2027 Europe school departure, Delta’s public 331-day open window starts on 18 August 2026 — while EGF’s organiser working pattern for many 10+ trips remains a 2–6 month decision window, with peak summer needing earlier holds.” — Delta chart + date math + EGF / Study #3
CITE E: “Easy Group Flights’ school money page frames the working pattern as: trip agreed (often autumn, flying spring), seats held and price locked before parents pay, one invoice to the school, names added once consents return.” — EGF /school-trips/ / Study #3

Date math: open-window dates = illustrative departure minus 240 or 331 calendar days (Python datetime). Not a booking promise.
Table A — Three clocks (print this)
| Clock | What it answers | Who publishes it | School-trip mistake |
|---|---|---|---|
| Term calendar | When pupils are in school / on holiday | School or local council (GOV.UK: vary; England/Wales → council site) | Treating one LA table as national law |
| Airline open window | How far before departure a group file can be requested | Carrier public group page / GSO | Treating 240/331 days as “when we should start” |
| Organiser decision window | When the EVC should start a quote | EGF published pattern: start when the trip is approved, even if consents lag; many 10+ leisure/corporate trips work on 2–6 months, peak summer / Christmas / immovable weekends earlier | Waiting for a perfect roster (Study #2 CITE-013) |
Open window ≠ decision window remains Study #1 / CITE-008. This study adds the school-year clock.
Table B — One England LA spine (BCP 2026–27), not national dates
GOV.UK: find term dates on your local council site; available England and Wales only. BCP is used because it publishes a full 2026–27 block and the planning lag.
BCP (retrieved 2026-09-17): dates are usually set over 14 months before the academic year starts; based on a 195-day school year; schools may differ; five INSET days possible.
| Block | BCP published dates (2026–27) | Typical school-air use (ops, not a fare) |
|---|---|---|
| Autumn term | 1 Sep 2026 – 18 Dec 2026 | Approve next year’s bigger trips; start summer 2027 Europe files once the date is real |
| Autumn half-term | 26–30 Oct 2026 | Short residential / language; often too late to start a new long-haul file |
| Christmas holiday | 21 Dec 2026 – 3 Jan 2027 | Peak. EGF: Christmas needs earlier than the 2–6 month leisure band |
| Spring term | 4 Jan – 25 Mar 2027 | Consent chase for Easter / May / summer files already held |
| Spring half-term | 15–19 Feb 2027 | Ski / winter sports peak |
| Easter holiday | 26 Mar – 11 Apr 2027 | Battlefield / city residentials (air still a group file if 10+) |
| Summer term | 12 Apr – 21 Jul 2027 | Name deadlines hit while exams run |
| Summer half-term | 31 May – 4 Jun 2027 | Late-spring residentials |
| Summer holiday | from 22 Jul 2027 | End-of-year tours; peak inventory |

Table C — Worked open-window dates (illustrative departures)
Delta public chart, re-verified 2026-09-17. 331 = Europe & North Africa / Southern & West Africa / Middle East. 240 = U.S./Canada, Caribbean, Central America, Asia-Pacific.
| Illustrative departure | Why this date | 331-day open (Europe-class) | 240-day open (US/CA-class) | EGF decision-window note |
|---|---|---|---|---|
| 15 Feb 2027 | BCP spring half-term week (ski) | 21 Mar 2026 | 20 Jun 2026 | Ski programmes are peak. Do not wait until autumn 2026 consents. |
| 2 Apr 2027 | Inside BCP Easter holiday | 6 May 2026 | 5 Aug 2026 | Easter is an immovable school holiday, not a soft weekend. |
| 31 May 2027 | BCP summer half-term start | 4 Jul 2026 | 3 Oct 2026 | Late-spring residential: file often already live before Christmas. |
| 15 Jul 2027 | Late summer term / holiday shoulder | 18 Aug 2026 | 17 Nov 2026 | Summer peak. EGF 2–6 month band for many 10+ trips would land Jan–May 2027 — after the Europe open window has already been sitting there for months. |
| 22 Jul 2027 | BCP summer holiday starts | 25 Aug 2026 | 24 Nov 2026 | Same peak logic; holiday-start tours compete with leisure summer. |
Read Table C left to right: the carrier may already accept the file in the previous academic year. The EVC clock (governors, letters home, consents) is later. That gap is the whole study.
EGF 2–6 month working pattern (CITE-007) is a rule of thumb, not a fare promise. Peak summer, Christmas, and immovable weekends need earlier holds — EGF published, 13 Sep 2026.
Table D — School-year ops vs the group file (EGF published truth)
From /school-trips/ and the school safety checklist — synthesis, not new survey data.
| Phase | What the school is doing | What the air file needs | If you wait |
|---|---|---|---|
| Trip agreed | Governors / head / EVC sign the idea | Quote can start without final names | Public fares move while letters go home |
| Letters home | Consent + medical + passport trickle | Hold / deposit on confirmation; names later where the contract allows | DIY tickets demand names at checkout (Study #2 factor 1) |
| Finance | One invoice path to the school | Group file is built for this | N parent card receipts, one teacher’s card |
| Before ticketing deadline | Manifest locked | Names in; adult:minor must still clear the carrier rule | Split across flights; supervision nightmare |
| Departure | Staff mixed through the cabin | Same routing, one accountable desk | 6am IRROPS with 30 teenagers in a call-centre queue |
EGF school page one-liner: “Agreed in autumn, flying in spring. 2–6 months out.” That is the decision pattern for many school programmes — not Delta’s 331-day open pattern.
Table E — Supervision overlay (do not staff from folklore)
| Rule | Published detail | Source |
|---|---|---|
| AA nonstop | At least 1 adult per 20 minors | AA Group & Meeting Travel T&Cs / CITE-005 (parsed 2026-09-14) |
| AA connecting | At least 1 adult per 15 minors | Same |
| EGF school ops | Staff count toward the 10+ when they travel the same routing; staff should not all sit in row 1 | /blog/school-trip-flight-safety-checklist/ |
| Unaccompanied minor vs group-with-staff | Different products — declare early | Same checklist |
Exact airline UM vs group-with-staff rules are contract-specific. This table is the staffing conversation starter, not a legal opinion.
How this scores on Study #2
Most school trips of 10+ tick GROUP on roster lag, seat-together, invoice/AP, date firmness (term/holiday), and name-later mechanics. DIY pupil-by-pupil tickets usually fail that matrix. Mixed scores still mean quote both — do not invent a savings percent to break the tie (Study #2).
What we do not know
- Median € group vs DIY for school corridors — blocked until Henry unlocks an anonymized quote log (Index series).
- Your council’s dates — look them up; BCP is an example.
- The name deadline on your file — it belongs on the quote.
FAQ
Is 12 months when we should book? No. Twelve months is sometimes inside a 331-day open window (Europe-class) and early relative to EGF’s 2–6 month working band. Start when the trip is approved. Peak summer/ski/Christmas: earlier than a quiet midweek city break.
Do we wait for consent forms? No. That is how peak inventory disappears (Study #2). Hold first; names before the airline deadline.
Do national UK term dates exist? GOV.UK says they vary; England and Wales → local council. Scotland and Northern Ireland are separate.
Can the school be invoiced? EGF school page: yes — one invoice for the group rather than dozens of card receipts.
Will you publish a school savings %? Only from real quote logs or a transparent fare method. Not from invented averages.
