Jah going to work is not macham holiday la like you see my post yesterday I started journey from early morning and getting stuck in the aircraft for 2hrs and ended in hotel at 1am and dinner at that time. Not easy bro. Very tiring. Oh I'll be in states for 17 days but them to and fro total 19 days.
Getting stuck on the tarmac is part of air travel, pii. Nothing you can do about it - always have something else to do - for me, I'd use the time to work and catch up on emails if possible.
You are certainly racking up lots of miles. Business travel is tiring indeed. I, myself, will be hitting 83k miles end of June. Sian.
