how do I get all shipping methods on the checkout page?

Hello,

I have two shipping methods on my checkout page:

1. Economy;

2. Standard.

and I want to get these shipping methods. I do the following:

{% for shipping_method in checkout.shipping_methods %}
   {{ shipping_method.title }}
{% endfor %}

But I only get one method - Standard.

Please tell me why I get only one shipping method, and how to get all (both) shipping methods?

Thank you!
