Partial effect and first-difference estimator

Hello guys,

I have a exercise for which I found an answer but i'm not sure of it. I need to estimate the demand for passenger flights in the US based on the following equation:

ln(passengers)it = β0 + β1 ln(airfare)it + β2 ln(distance)i + ci + uit

with ci is the individual effect and uit the idiosyncratic error term.

I need to say what is the estimated partial effect of the airfare on the average number of passengers per day.
If it have that results (see attachments), can I say the increase of 1% in the air fare leads to a decrease of -0.9% of the average number of passengers per day ?
