I have 2 options (really many more so feel free to make a recommendation). I plan to fly to JFK but could get from CMH to any other gateway city. Would you take Finnair through Helsinki (an 8 hour flight followed by an 11.5 hour flight) or Cathay Pacific through HKG (16 hours followed by 3 hours and 10 minutes)? Qatar and JAL are also options from JFK.

Thanks.
