Airbus had developed a high-density version of the A330 which was snapped up by Cebu Pacific in 2014. The Cebu Pacific A330 remains the world’s most tightly configured with 436 Economy seats. The aircraft is configured with nine abreast seating in a 3-3-3 configuration which gives passengers just 16.5 inches (41.9cm) between armrests, which is a 3.75-5 centimetre reduction off the standard economy configurations found in most economy cabins. However, the new Airbus initiative would see the certified limit for the A330 lifted from 440 seats to 465 passengers. This would also require the installation of much smaller galleys which have proved very unpopular with cabin crew.

Our rating system is rated from one to seven stars on safety – with seven being the highest ranking. Within each airline, you will find the country of origin, airline code, booking URL and seat map information. The rating system takes into account a number of different factors related to audits from aviation’s governing bodies, lead associations, as well as the airlines, own safety data. Every airline has a safety rating breakdown so you can see exactly how they rate. Over 230 of the airlines on the site that carry 99 per cent of the world’s passengers have a product rating. Given that low-cost, regional and full-service carriers are so different we have constructed a different rating system for each which can be found within each airline.
