Baltic-bound travelers from the Valley of the Sun face an inescapable truth: there's no nonstop path to Riga, and business class from Phoenix to Riga requires a thoughtfully chosen connection, since neither American, Delta, nor airBaltic operates direct service on this city pair. The most reliable routing I've found after years of booking this corridor involves flying Delta or American across the Atlantic to a major European gateway—Amsterdam, Paris, or London are your best bets—before connecting onward to Riga, often on airBaltic's compact but comfortable Airbus A220 fleet, which the Latvian flag carrier uses almost exclusively for its short regional hops. Delta's transatlantic leg in Delta One, with its suite-style seating and sliding privacy doors on 767 and A330 aircraft, remains the most consistent hard-product upgrade over American's older business cabins, though American's Flagship Suite on select 777 and 787 routings to London or Paris is worth chasing if your itinerary allows a same-day connection.
The real skill in booking this route lies in the connection city selection, not the transatlantic carrier. I've learned to favor Amsterdam Schiphol or Paris CDG over Heathrow for the Riga leg, simply because minimum connection times are more forgiving and airBaltic's gates tend to sit closer to arriving international flights, reducing the anxiety of a tight transfer after an eight-hour red-eye from Phoenix. One insider tip that rarely surfaces in generic guides: airBaltic frequently releases inventory in its slightly upgraded "Business" seating—essentially economy seats with a blocked middle—so don't expect a lie-flat product on the final hop; instead, treat the long-haul segment as where your comfort budget matters most, and consider scheduling a few hours' layover to shower and reset at a European hub lounge before the shorter Baltic connection.
Late spring through early autumn—May through September—consistently offers the most favorable fare windows and the mildest Baltic weather for arrival in Riga's cobblestoned Old Town. Given the multi-carrier complexity of this route, setting up automated fare alerts is genuinely the smartest way to catch premium-cabin pricing dips before they vanish.
