If you are hungry for a very long time then we can say that you are starving. For example. When you say "mom please give me some food I am hungry" , here you say hungry because you have not ate for few hours may be. But when a begger says " sir please give me some food I am starving" , here he uses starv because he has not ate from few days.

according to the dictionary, to starve means to "suffer severely or die from hunger" So one could starve but not die. I was not aware of this. I would have thought both sentences had the same meaning.

Hi Both are correct. The Second one is more common! There is an exaggeration involved which makes it funny...

Thank you

Both sentences are negative and can be interpreted as being rude depending on the context. First sentence is very extreme, meaning you really hate airplane food. The second just mean you do no like airplane food.
