Until about a year ago we had the 31,500 alt restriction for dispatch with a single pack.
Now the company (major UK Airbus operator) have changed to what is pretty much a direct copy of the Airbus MEL. This gives us the options of no altitude restriction provided the speedbrakes work. If your speedbrakes are U/S and you have a single pack then 31,500' is your max.
You have to check the MEL very carefully especially with respect to MSN number as some aircraft are restricted to 37,000 on a single pack even with the speedbrake working.
