Article summary

This article provides frequently asked questions (FAQs) for various airlines, including American, Delta, United, Southwest, Frontier, Hawaiian, Air Canada, Alaska, and JetBlue. It covers topics such as cancellation policies, adding bags, free carry-ons, changing flights, military benefits, and seat selection for each airline. Additionally, there's a section on Engine-specific FAQs regarding travel credit, direct bill refunds, booking fees, airline rewards, and flight visibility in airline apps.

 

  • What is Engine Travel Credit?

    • Engine Travel Credit is stored in your account and can be applied toward future bookings on Engine. 

    • Credits are valid for 1 year from the date issued and work just like cash on our platform. $1 Travel Credit = $1 USD.

  • Can I be refunded with Direct Bill?

    • Your refund options depend on your ticket type and the timing of your cancellation:

      • Within 24 hours of booking (and at least 7 days before departure): You’re eligible for a full refund, with no impact on your Direct Bill statement.

      • After 24 hours: Most tickets become nonrefundable. Refundable fares may qualify for a credit memo. Flex for Flights purchases may be refunded as Engine Travel Credit.

    • Note: Direct Bill transactions follow standard airline refund policies. The 24-hour window remains your best opportunity for a full refund.

  • Is the booking fee refundable?

    • No. The Engine booking fee is nonrefundable.

  • Is my flight eligible for airline rewards?

    • Yes! You can earn airline loyalty points or miles on eligible flights. To ensure this: 

      • Add your loyalty number to your Engine profile before booking, and we’ll automatically include it.

      • If you’ve already booked, contact the airline directly to confirm your loyalty number is attached.

      • Member Support can assist in updating loyalty numbers such as frequent flier numbers and known traveler numbers on flights booked through Engine.

    • For future trips, save your loyalty number in your Engine account so it’s always ready at checkout.

  • Why is my flight not appearing in the airline's app?

    • It may take up to 48 hours for your booking confirmation to be reflected in the airlines systems.

  • Can I change my flight?

    • Yes! If you booked through Engine, you can change your flight's date, time, or airports — either in the app or by contacting Member Support.

      • Note: Flights on the ultra low-cost carrier Frontier must be changed directly with the airline. All other carriers can be changed through Engine.
