Who are the "many people"?
It would be desirable to be on time for an inaugural flight but there could be a million and one reasons for the delay,not least the weather which was awful last week, they were about 20 mins late by the time they arrived on stand. You only need a missing passenger or photoshoot at BCN to miss a slot. Vueling delivered 91% of their flights on time in March, not bad going.
