Compares pre-acceptance work with the entered acceptance deadline.
Airport-change connection planner
Include the airport transfer in your connection time.
Measure the work from scheduled arrival to onward acceptance, then from acceptance to the gate. The tool uses only the durations and carrier cutoffs you enter.

Airport Change Connection Planner
Every field starts blank. Use minutes from current itinerary, airline, airport, border, and ground-transfer information. Enter zero only when a step really takes no time or does not apply.
Connection check
13 fields still empty.
Enter the scheduled window, both official cutoffs, and every task duration. Blank values are not counted as zero.
Compares all entered work with the entered gate deadline.
- Entered work before acceptance
- No durations entered
- Entered work after acceptance
- No durations entered
- Acceptance deadline on the relative timeline
- Waiting for window and cutoff

Calculation
Window - acceptance cutoff - pre-acceptance work.
Window - gate cutoff - all entered work.
Missing or invalid timings
- Schedule and official cutoffs: 3 missing.
- Before acceptance: 7 missing.
- After acceptance: 3 missing.
The margin uses only the numbers you enter. It cannot tell you whether the connection is protected or whether you will make it.
Task list
Leave unknown timings blank.
This list mirrors the tool without turning a blank into zero. It remains useful in print and shows which timings still need checking.

How it works
Check the airline acceptance and gate deadlines.
Why acceptance is checked first
Heathrow and Gatwick each show how a separate-ticket connection can move through arrivals, baggage, a landside handoff, and a new check-in. For an airport change, IATA's baggage guidance identifies the airport change as a collection endpoint, subject to carrier policy. The first calculation therefore asks whether all entered arrival and ground-transfer work ends before the current acceptance cutoff you entered.
Why the gate gets a separate check
After check-in or bag acceptance, you may still face security, terminal movement, and the operating airline's boarding deadline. The second calculation therefore uses the gate cutoff you enter.
Why the tool has no airport presets
IATA describes minimum connecting time as a location-specific official interval. Airports and airlines publish their own current processes and thresholds. This tool has no MCT, traffic, route, queue, schedule, terminal, border, baggage, security, or gate feed. A default would be a guess, so every timing starts blank.
How to interpret a signed margin
A plus sign means the entered tasks end before the entered deadline in the arithmetic. A minus sign means they end beyond it. Neither sign predicts what will happen. Recheck the ticket structure, operating carriers, airports, ground route, immigration and transit requirements, baggage path, accessibility needs, and recovery responsibility before relying on the plan.
