Some new airlines/routes that I heard were going to start in 2017 were:
Eurowings from CGN
Norwegian from TXL/MUC
TK from LUX(that was a while ago though)
Hainan from CTU(might be a bit wrong on that one)
Sichuan airlines (not sure from where in china)
Suriname from GEO (And quite a big possibility that it will operate with their A340-300!)
Vivaaerobus from MEX
Anyone know/heard of any other possible new flights/routes to JFK?
