How to apologise if you are late to meeting
Instead of offering up a reason or excuse for why you were late, focus your apology on the impact you’ve made or the problems you’ve caused. Say something like “Sorry for keeping you waiting” or “I’m so sorry for taking up more of your time” or even “Thank you for your flexibility.” If you show everyone that you’re sorry for using up their valuable time, your apology will sound much more sincere.
