Every morning Anna commutes

[Bassim]

I am wondering if my sentence is grammatically correct.

Every morning Anna commutes about two hours, during which she can snatch some sleep, if she finds a vacant seat.

teechar,
Thank you for correcting my mistakes.

I am only wondering if the comma after "morning" is mandatory or if it could be omitted. I wanted to use a comma, but then thought that maybe I could omit it, but probably that was wrong.

I'd accept the sentence without the first comma.
