I personally prefer flying to target area, because that way you have a way better situational awareness of what is going on instead of warping straight into fire. I play with almost all set to hard and in SAM-rich enviroment I drop chaff from time to time and NEVER fly straight for more than a few secs. TY90 and LD2000 Anti-air systems are extremely lethal, so try to avoid them as you´d try to avoid plague. Fly low and fly fast. That usually works for me to get the job done, but not always. That´s why it´s so much fun. Good luck!!!
