second: been there, done that and failed. ( still don't know why Sabena flew to Madras )
third: recent developments show the great risks e.g. overflying Ukraine. What with Russian territory/sanctions in the future ? Nobody knows. Uncertainty is a killer in business.
fourth: Where is the real money? Recent information shows that the so called Chinese middle class has been widely overestimated. In numbers but also in purchasing power.
fifth - together with first: "money no have"
Pro:
The Middle East / Arab / Gulf states is served by several of their own airlines, so they deserve some Belgian competition
Korea needs attention.
Direct flights to Indonesia and Phillipines. Their airlines failed in the past. ( ok, so did Sabena ) But with good strict managment, these lines could work.
The garbage bin: Pakistan, Bangladesh, Myanmar. If SN is strong in Africa with destinations where others are afraid of, why not make money from Asian questionable destinations?
