Uncertainty

[teechar]

But I thought that some of my fellow forum members might like to know that some teachers might insist on "... because no regular or direct flight is available from my hometown, ..."
The traditional rule is to use the singular verb to match a singular noun after the conjunction "or." On the other hand, one would say that "no regular or direct flights are available."

You are absolutely right! Thank you for pointing that out.
I somehow had forgotten to change "flight" to "flights".
In future, please do not hesitate to point out any mistakes or oversights. I am always grateful when people do.
