Jetblue Mint BOS to SFO

JetBlue Mint is hands down the best first class product out of all other domestic carriers. The upgraded seating and service is available on all transatlantic and select coast-to-coast flights. With its fully lie-flat seats (massage functionality!), the largest TV on a U.S. airline, first class meals and service, and even suites equipped with their own privacy doors, no other domestic airline comes close in the air at this tier of service. I took this particular flight right around when they first introduced this service and amazingly, they've actually improved upon it since then.
