Sorry if this is the wrong place to ask, but I figure people here would know:

Applying now (new application system, after it moved off of airlineapps), and I don't see anywhere to upload letters of recommendation, only a yes/no checkbox for whether I have any LORs. Looked through every page and can't see anywhere to upload them. Should I assume I'll just provide them later if I'm ever contacted by United?

Thanks in advance.
