used to fly their daily B744's LAX
(UA841/UA842) the F/A's & tech crew would overnight in AKL
southbound for 48 hours, then operate the AKL
shuttle, overnight for another 23-24 hours before departing again for LAX
I think Qantas crew have a similar arrangement for crew who operate SYD
on the QF107/108 pairing? ie. 48 hours in LAX
the first time, then they either layover in NYC or sometimes do the shuttle back to LAX
, either way they layover in LAX
again for another 24hrs and then head back to SYD
. However Qantas crews on the A380 ex SYD
arrive in the morning into LAX
, have around 36 hours layover before departing the following evening back to Australia.
Usually the airlines have formulas or agreements in place with the relevant unions on layovers.
