أنجليزي term (edited): ... no blame for giving your flying lessons a miss.

As they say; short and sweet ^_^
First, you, my dear friend, did not bother with giving more appropriate context (you see that's why no one bothered to way-in).
Second, all I did was taking "flying-" out on the similarity here, like if it were "go on missing your lessons".

= So, take my phrase, and put it in the original text, and read all as a whole, then decide for yourself, and you will find us here waiting for your feedback
// ... go on missing your lessons ... //

Don't be a Stranger ^_^

المتحدث يلوم الشخص عن إهماله في تحديث اللافتة لجذب الزوار لحضور دروس الطيران، لذا فهي تعني تغيبهم عن حضور دروس الطيران التي يقدمها و ليس تغيبه هو عن الحضور

You can also paraphrase the sentence in English to understand the meaning more:
(no one could be blamed for deciding not to attend your flying lessons) based on which the Arabic translation will be as follows:

لا يمكنك إلقاء اللوم على أحد إذا ما قرر عدم حضور دروس الطيران التي تقدمها
