  1. Minimum-time route location islinked to the jet stream Eastbound: New York - London fly in the jet stream Westbound: London - New York avoid the jet stream Irvine et al., 2013, Meteorological Applications

  2. Winter weather types are characterised by the jet stream Eastbound Westbound W1. strong zonal jet W2. Strong tilted jet W4. Confined jet Irvine et al., 2013, Met. Apps. Pressure pattern at flight level (black) and jet stream (red). Daily minimum-time routes between London and New York (blue).

  3. Contrail formation regions are linked to the weather pattern FL300 FL340 FL390 W1. Zonal jet W2. Tilted jet W4. Confined jet Eastbound routes Westbound routes tropopause

  4. Route time varies accordingto the weather pattern

  5. Jet stream location is related to the North Atlantic Oscillation Positive NAO jet stream further north Negative NAO jet stream further south Diagrams from: http://www.ldeo.columbia.edu/res/pi/NAO/

  6. Frequency of winter weather patterns
