Having already declined an offer of employment, why would the Company want to give you a second offer now that a left seat is possible.Did you give a valid reason for not coming originally? We look to employ people for many reasons, among which, is a desire to work for Emirates.....not JUST the fact that it's got to be left seat or nothing.
Still, good luck if you do decide to come for interview.....you may just need it!
