Using a flow to get to a legacy is a different matter. Yes you could get to American without a degree in that case. Although in the time it will take you to flow up will be WAY longer then the time it takes to get some sort of online degree and hired at US Legacy.
You are very competive for US legacies now, but I'm sorry to say no 4 year is a huge hole. My friend worked in hiring at a US Legacy. He told me that those hired without 4 year were very limited and had extremely important connections. That said applying now does not hurt obviously. Have a look at Allegiant, JetBlue, and Spirit. I bet you get a call from one of them. All far better positions then the rubbish Norweign is throwing out.
