Laker duly reapplied to the CAA for permission to operate eleven weekly "Skytrain" services each way between London Gatwick and New York's John F. Kennedy Airport (JFK) during the summer and seven weekly round-trips during the winter. The summer schedule was to be operated with Laker's brand-new DC-10 widebodied jet aircraft to take advantage of increased demand he anticipated for his new low-fare service during the peak months from June to September as well as of the DC-10's low break-even load factor of only 52%. The winter schedule was to be operated with 707 narrowbodies as specified in Laker's original application to the ATLB.
