If you elect to use a mobile boarding pass and have purchased a Business Select Fare, your drink coupon eligibility will be noted on the mobile boarding pass. To receive your complimentary premium drink during your flight, simply show the drink coupon portion of your mobile boarding pass to the Flight Attendant for validation. Note that this is only applicable for flights over 175 miles.
Be sure to save a copy of your mobile boarding pass to your mobile device prior to takeoff so you can easily retrieve it during your flight.
