Ryanair survey (questionnaire)

Dear Participants,

I am a regular flier with Ryanair and that is why I chose the company as a base for my Master Degree dissertation topic.
I am conducting a survey on Ryanair and customers` perception of the brand. In the following questionnaire, I would like to know your perception and behaviors related to satisfaction, convenience, loyalty, and preferences to emerging destinations that the airline offers. Since this survey is a part of my master thesis, your participation is essential for its successful completion. Your responses will be anonymous; data will be combined and analyzed as a whole. Please attempt to answer all the questions.

Your participation in the study will be greatly appreciated.

Thank you very much for your time and assistance!

What exactly do you mean by :
popular destination / popular region / less popular destination / emerging destination / emerging region / developing destination
I find it all rather ambiguous and confused.
