Compare the fare to Emirates, their B777s have similar seat width, A380 much better. Food, entertainment and 30kgs baggage included. Work out if the extra comfort is worth the extra money.
Low costs generally have much cheaper one way fares than full service airlines which typically charge the same as an APEX return if only going one way.
Its simply another option available, if you don't like what's on offer shop around. One stop flights on that route and dates are coming in around the $2300 return mark with the ME 3.
