RAML uses YAML indentation to define the hierarchy of resources and the HTTP methods that apply to each resource. The GET operation for a specific flight belongs inside the resource that represents that path, typically /flights/{flight_id}. If the GET block sits at the same indentation level as the {flight_id} resource, it isn’t actually inside that resource and the parser will flag an error or misinterpret the structure. Indenting the GET method one level deeper signals that it is a child operation of the /flights/{flight_id} resource, which fixes the structure and associates the method with the correct path.

Adding or removing a slash wouldn’t fix this indentation-related syntax issue, and moving the GET to a new resource under /flights would change the path semantics. Removing the GET would not address the underlying formatting error.
