I think you should go to the first OD available to you, and take the job at the domestic carrier if it's available. Emirates hired me with 8 months of domestic cabin crew experience. A great thing to tell them at this point is that you really enjoy your job, but would like to travel internationally and be able to help a wider range of people/ your people skills are not being used to their full advantage. Either way, domestic or international, you'll love the job!
