10 Polite Ways to Say You're Running Late (With Examples)

Running a few minutes behind happens to everyone. The tricky part isn't the lateness itself — it's finding the right words to say so, quickly, without over-explaining or sounding stressed. A short, well-worded heads-up goes a long way toward keeping things professional.

Why a short message works best

Your manager or team doesn't need a full explanation in the moment — they need two things: that you're aware you're late, and a rough sense of when you'll arrive. Save the details for later if anyone asks.

10 ready-to-use examples

1. Running a few minutes behind — see you shortly! Good for informal team chats.
2. Stuck in traffic, but on my way. Should be there by [time]. Gives a concrete ETA when you have one.
3. Sorry for the late notice — I'll be about 15 minutes behind schedule. Acknowledges the short notice without over-apologising.
4. Quick heads up, I'm running late this morning. I'll update you on my ETA. Useful when you don't yet know exactly when you'll arrive.
5. Apologies for the delay — I'm on my way and should arrive shortly. A safe, formal option for a manager or client.
6. I'm running behind due to a transport delay — I'll keep you posted. Adds a brief, non-detailed reason.
7. Sorry, running a bit late! I'll be there as soon as I can. Casual and warm — good for a close team.
8. Heads up — I'm delayed this morning, expect me around [time]. Direct and easy to scan.
9. My apologies, I'm running late. I'll join as soon as I'm able. Works well for a meeting you're about to miss the start of.
10. Running late — I'll fill you in on the details when I arrive. Keeps things brief while signalling more context is available if needed.

A few quick tips

• Send it as soon as you know. A message before your start time is always better than one after.
• Give an ETA if you can. Even a rough one ("about 20 minutes") is more useful than "running late" alone.
• Match the tone to the audience. A client or manager usually warrants a more formal message than a team chat.
• You don't owe a detailed explanation. "Running behind" is a complete sentence — you can share more later if it's relevant.
