Flying at candle-lighting time: what do people do?

Has anyone ever tried to light Hanukkah candles at an airport before a flight? We’re flying out of Pearson (AC direct to Israel) right around candle-lighting time, and I’m trying to figure out what’s realistic. The airport chapel is pre-security, which may make timing tricky.
If you’ve done this at Pearson or any other airport, how did you handle it? Any tips or experiences would be really helpful.
