As long as you show concern for your Salah, and you feel bad for having to delay it, and you could not find a practical way to offer it right on time, then you would not be considered as negligent with your Salat, and hopefully you will be granted the full reward. But make sure that your Salat never becomes Qadha’, as that is a major sin. As long as it doesn’t become Qadha’ then you are ok.
