MJV is, according to a very knowledgeable FR worker on this website (no, not me! Haha), planned to become a base early next year, for it generates high yields and is a popular place. So, FR might well wish to compete forcefully on this route in order to safeguard it, but who knows? FR has three daily flights from LON to MJV, of which 2 are from STN and 1 is from LTN.
