If you're thinking about running Google Travel Ads for flights, having IATA certification is usually a must,Its how Google makes sure advertisers meet their policy standards.If you’re not IATA-accredited yourself,you can still get in by teaming up with an agency that is.Just dont try to work around the system - Google’s pretty quick to detect policy violations,and accounts can get suspended or banned before you even get going,best bet is to use legit ad accounts,keep your ads transparent,and start with a small budget to test and improve your performance safely
