Big data has been a buzz phrase for a while now and at OAG we know all about big data handling, as we do data for the world’s airlines. In fact, we’ve been doing big data since long before ‘big data’ was even a thing.

So, we know that when there’s more data than you can possibly know what to do with, sometimes what you need is someone else to package it into nice, small, digestible chunks. OAG Take-Off's metrics does just that, providing you with a snapshot of the world’s Top 20 airlines, placing key data at your fingertips.

Airline seats is the metric used to qualify for inclusion in the ranking of Top 20 airlines, but OAG Take-Off gives you so much more – the scale of the route network, fleet and aircraft orders, passengers and growth, among other metrics.

These Top 20 airlines make up 41% of all global scheduled airline capacity and reflect many of the major trends we see in the industry:

• Low-cost carriers continuing to strengthen their foothold in the market (easyJet rises from 9^th place in our April edition to be ranked 8^th).
• Chinese carriers making their mark (Air China moves up from 11^th to 10^th, while China Southern and China Eastern remain ranked 6^th and 7^th, respectively).
• Rapid changes in fast growing Asian markets as Lion Air drops out of the Top 20 but IndiGo storms in, ranking 17^th. The sheer scale of the IndiGo aircraft order book makes this airline one to watch as we see it elbow other airlines out of the way and continue its move up the rankings in future editions of OAG Take-Off.

While big data matters, insight is everything. That’s what OAG Take-Off provides for the world’s major airlines.
