I have a flight on Tuesday at 7:30am, which means I will probably not be able to daven with a minyan, nor will I have access to a shofar. Is there anything I can and should do as tashlumin for missing shofar blowing?
Yes, there is. Sit down for five minutes and contemplate about your life and what you can improve in regard to your relationship with Hashem, with people, and how you cn better yourself. That is the purpose of the sofar, and if you can’t actually hear it, you can perform it’s purpose.
