Jetstar has been voted the world's best low-cost airline in the respected Skytrax annual survey.

Skytrax collated the results from 14 million respondents, and 5 million in the low-cost carrier category.

Jetstar also beat Virgin Blue to take the best low-cost carrier in Australia-Pacific and the best cabin staff for Australia-New Zealand.

The win contradicts a survey of 4000 people by Australia-based Choice magazine, which found that passengers were least satisfied with Jetstar.
