How to do an MCT Search

Minimum Connecting Time (MCT) data defines the shortest permissible connection time at an airport. Searches require at minimum an airport code or airline code, and can be refined using any of the variables listed below.

Searching a Specific File

Specify the file name directly, or use a descriptive reference:

Use MCT files updated in the second week of January 2026

Comparing Two Files

Specify both files to compare. To compare the latest update against the previous one:

Compare the current to the previous MCT updates for LHR

Examples

MCT for LHR

MCT for LHR Terminal 2

MCT for LHR I-I

MCT for SQ in LHR

MCT for SQ in LHR submitted by BA

MCT Types
