All current Britax Harness-2-Booster Combination Seats (Frontier 90, Pinnacle 90 & Pioneer 70) will be certified for aircraft use in early February. This change will be retroactive to all current models, and an FAQ and addendum will update this on the Britax website soon. An updated manual will follow in early February.
The updated instructions for airplane installation will instruct you to route the aircraft’s lap-only seatbelt in front of the ClickTight compartment. This installation method will ONLY be approved for installation on an airplane. Since the Pioneer 70 lacks the ClickTight feature, you will route the plane’s lap belt the same way you normally would on this particular seat.
More details to follow soon. We’ll share ‘em when we have ‘em!
