I have no problem with field standby. To preserve our evening Europe banks at EWR/IAD/ORD or mid day Pacific banks at SFO or LAX or South America evening departures at IAH, it makes sense. A few shifts of airbus and 737 field standbys make sense as well. It should pay 5 hours towards monthly reserve guarantee and an agreed upon number of crews for each equipment type in each base per day should be set and agreed upon monthly when the system schedule committee meets with the company.
