There’s an amazing deal on United Airlines between Boston and Seoul, Korea (ICN) in FIRST CLASS!
Normally flights from USA to ICN can run from $900-$1,200 in Economy so by paying just a bit more you will fly in First Class lie-flat seats. Not only that, you will earn about 30,000 United Airlines miles which will get you free flights (depends on where you are going, but at least 3 one-way domestic tickets).
Availability: Mon-Thur departures, 14 day advanced booking. Wide availability until May of 2015!!
Even if you don’t live in Boston to take advantage of this, I would fly into Boston just to fly First Class, especially if you are in the East Coast.
