I travel 8-10 times a year to conferences and meet clients (not a huge amount but still considerable) and my advice:
1. MBP is god-like for travelling, definitely heavy but feels like a PC and comfortable to use anywhere.
2. Ipad Pro with magic keyboard for working on airplane, taxi, coffeeshop with no comfortable table etc... (although you can't code you can complete other administrative tasks) or communicate with the team.
3. I have a bag that fits 5 chargers, my Kindle, Ipad and MBP with a place for passports and documents. I use it and take it everywhere, very easy to load and unload.
Finally, crazy advice, but try working from bed or lying down on a couch, your back will say thank you
