I'm going from NYC to Porto for a week in July. I can either fly TAP Executive Class from Newark to Porto or KLM Business Class there and Premium Comfort on the way back. TAP is a direct flight and has better flight times, but getting to Newark and back is a real pain compared to getting to JFK for KLM. KLM would transfer through Amsterdam has less good flight times, but might be a better flight experience and all my miles are on SkyTeam . . . What would you do?
