I'm guessing you're an APS-C user. If you have the budget, a 70-200 L/70-300 L/100-400 L lens would be nice. If you don't have a budget, you're not planning to move to FF soon, and you're not into sports that much, a 55-250mm would be very nice. It's colors and focusing is surprisingly good especially in good light. That 18-270mm isn't that good a performer especially that you have a 10-22 and a 24-105 lens but if I were you, I'll not dispose of it. It's still usable when you want to bring only one lens. But just the same, if I were in your shoes, I'll bring the 10-22 and 24-105 if I really like to travel light.
