Also the immigration in let's say USA may wonder about why you don't have a British stamp in your passport if you're arriving from UK on an American passport...
If you need a visa for the country you are visiting then obviously you show the passport with the visa in. Airline doesn't care if you have dual nationality - they just need to ensure that you have the appropriate travel docs.
And entering the US is certainly not an issue. Mrs Schmidt is a UK/US dual national and only ever uses her US passport to enter the US and for travel to/from Mexico and Canada otherwise she uses the British one. Never gets asked anything.
One time though we took the TurboJet from HK to Macau once where she left HK on her UK one and because she was running very low on space, decided to use the US one to enter Macau. She confused the immigration guy in Macau for ages before we realised he was looking for the exit stamp from HK, so showed him the British passport with the HK exit stamp and he then stamped the US one.
