Certainly the intention of the powers that be is to preserve existing levels of standby. It will certainly make it harder to book leave and courses with a smaller pool of people, but 1st and 2nd Standby is likely to continue unchanged except in exceptional circumstances - as has always been the case.
TOTD. It always used to take 5 crews per flight to man first, seconds, the FI, leave, courses, etc. If the maths were corrrect before how is this sustainable now with fewer crews?
