Flying economy just isn't what it used to be. Flying business class however is better than ever, featuring a never ending supply of flat beds, champagne, steaks on a plane and all sorts of swanky perks to make you feel like a true VIP from curbside to baggage claim. The best part? Sometimes you can experience it for yourself at prices lower than premium economy...
Say Bonjour to Paris, London, New York, Los Angeles, San Francisco and Honolulu, or just a couple of those! It's your choice. American Airlines, British Airways, Iberia and Finnair have teamed up to conquer the business class market in Paris, offering insanely low fares to places which are hardly ever low. You'll start your journey in Paris and can transit through London or just fly direct to the US. Once across the pond, you can stopover in New York, Dallas or Miami before heading to Los Angeles or San Francisco. It get's better, Hawaii is included. Think about it like this: you're getting two trips in one and flying economy would take two separate trips, which would end up costing more...
For easiest availability you'll want to stick to September 2016-March 2017. There are sporadic dates outside of that range, and anything is worth a search but for these incredible prices you'll do best if you search around there. Use GoogleFlights to experiment with stopovers wherever you wish!
How To Book
The easiest way to play around is to use Google Flights multi city search tool. It's easy, flexible and powerful. I made an example from Paris to New York, to Los Angeles, back to New York before heading back to Paris. If you prefer Honolulu to West Coast USA, you can just sub it in. Google flights will give you your booking options. You should be able to book this from Finnair, American Airlines or Iberia. Wherever you book, you can still earn miles on any OneWorld airline. If you have trouble, consult a travel agent or try another site or online booking agency like Expedia or GotoGate. Here's my example you can start with. Google flights will send you directly to a site to book easily.
Important NOTE: You can put American Airlines itineraries on hold for up to 72 hours. Alternately, you can book this and cancel for free within 24 hours.
You are allowed two stopovers on this fare so if you want to see a few places, do it. You can easily stop in New York, Dallas, Miami, San Francisco or Los Angeles before heading to Hawaii, or alternately stop on the East Coast before heading to West Coast if you don't have interest in Hawaii. I'd credit these flights to Alaska Airlines, American Airlines or British Airways. If you credit an itinerary like this to British Airways and fly two segments on British Airways, you'll earn instant Silver status, which is a year of free lounge access and perks no matter what cabin you're flying in..
