I'm looking at booking a flight to Spain. The option that Delta gives me is to depart Texas at 8:06AM (6hr layover at JFK) and arrive in Barcelona at 9:55AM. I can save nearly half by booking 2 separate tickets (both with Delta); depart Texas at 8:06AM to JFK (12:55PM), then JFK at 4:20PM to Barcelona (arrive at 9:10AM - w/ Paris Layover). Am I missing something? Is 3 hours not enough time to check out of the domestic flight and reenter on an international - granted I will have luggage (12 day trip). Thoughts? Comments? Price difference is $1,400 and $800 round trip.
