On a boring afternoon curiosity dragged me to the EK profile link on their company site. Yes, that boring.
The overriding message was a belief in open markets and free competition.
Indeed, words never equate to action. However, SpiceJet is not even close to any significant competition FZ or EK perceive as a genuine threat to their ambitions.
Regulatory approval would be the least of SpiceJets problems. Their gross incompetence and ineptitude would be more significant barriers in establishing and sustaining an overseas base.
