Nope its not bigger than a 733 its longer, from a customer point of view nothing changes apart from a longer queue to check in or to collect your luggage, bigger aircraft 'statement' implies err well a bigger aircraft.
So longer isn't bigger? Based on this logic a 757 isn't bigger than a 737 then? Where's my physics' textbook - somebody's re-written the rules...
In the context used, a bigger aircraft means more seats
meaning THOUSANDS more opportunities to jet away to popular hotspots
