Possibly a stupid question but how many more 737 sized airframes could be accommodated at Luton overnight in July with initial departures around 6 am or 7 am (along with the rest of the morning rush), not just for ramp space but also passenger security screening capacity of the terminal ? Am guessing that this is a major constraint on the likelihood of Ryanair basing more aircraft at Luton for the time being, or at least until the builders start doing major work.
