By Chinedu Eze Many industry stakeholders, including airline operators have over the years lamented how Nigerian carriers have failed in international flight operations. According to industry observers, without effective interline arrangement with other international carriers that can take their passengers farther, Nigerian airlines would not only continue to perform poorly on international routes, also they would barely make profits on such ventures. In fact, THISDAY learnt that the airlines that have operated international destinations in Nigeria recorded losses, which were moderated by revenues they were making on domestic services.
