the thing i find interesting is that this call sign methodology is not consistently applied. for example, the LHR - YUL sector still uses the 'speedbird niner fife' call sign, while the return uses '8 yankee golf' (as opposed to niner four). i would have thought if they would use one call sign methodology. i'm pretty sure tho that the YUL - LHR uses 8 yankee golf due to the fact that they follow speedbird 294 all the way across the pond.
