Frequently Asked Questions

What exactly are interline agreements?
Think of interline agreements as a handshake between airlines. They allow different carriers to cooperate on things like ticketing and baggage handling. So, if you're flying from one place to another and need to switch airlines, these agreements make the transition smoother than a hot knife through butter.
How do interline agreements benefit passengers?
For travelers, these agreements are a godsend. They mean you can check your bags once, and they'll find their way to your final destination, even if you're switching airlines. Plus, booking flights across multiple airlines becomes a breeze, often with a single ticket for the whole journey.
Can you earn frequent flyer miles with interline agreements?
Absolutely! When airlines buddy up through interline agreements, they often allow you to earn frequent flyer miles on your account, even if you're flying with a partner airline. It's like getting extra credit for classwork you're doing anyway.
Are interline agreements the same as codeshare agreements?
Not quite, though they're cousins in the airline family. Interline agreements are about the logistics – think baggage and ticketing. Codeshare agreements go a step further, allowing airlines to sell seats on each other's flights as if they were their own. Both make life easier for travelers but in slightly different ways.
Do all airlines have interline agreements?
Nope, not all airlines play in the same sandbox. While many major carriers have a web of interline agreements, some budget airlines choose to fly solo, keeping their operations more straightforward but limiting their reach.
How can I find out if airlines have an interline agreement?
Your best bet is to check directly with the airline or peek at their website. Customer service can also give you the lowdown on whether they're in cahoots with other carriers and how that might benefit your travel plans.
What happens if something goes wrong with my flight under an interline agreement?
If the skies get a bit bumpy and there are delays or cancellations, airlines in an interline agreement usually have your back. They'll work together to rebook you on the next available flight, even if it's with a different carrier. It's like having a travel safety net.
Can interline agreements affect the price of my ticket?
They can, but not always in the way you might think. Sometimes, these agreements can lead to better deals, especially for complex itineraries. Other times, prices might be a bit higher due to the added convenience and flexibility. It's all about finding the right balance for your wallet and your travel needs.
