On the subject of criticism regarding Jet2 not advertising in Krakow (or other destination cities) the most likely explanation is expense. A hub airport (LBA, MAN, NCL, BLK etc. in the case of Jet2) is bound to command the bulk of limited marketing resources based on simple economics. Advertising in the Granada/Yorkshire TV regions, or in major regional newspapers such as the Yorkshire Post, the Manchester Evening News or The Journal reaches the largest number of potential customers for the least marketing spend. A well-placed advertisement in Leeds or Manchester can attract business for the entire operation out of those cities. However, a similar advert in Krakow will attract potential business for ... er ... is it 4 flights per week? Afew adverts there, placed at the usual going rate, will soon erode any potential profit for the service. Multiply this principle by all the overseas airports and it quickly becomes apparent why Jet2 - and all similar businesses - must concentrate limited marketing resources where the greatest financial return will be achieved. Each advert placed in Leeds or Manchester helps to fill 100+ flights per week. An advert placed abroad - possibly at similar cost - promotes only a small number of flights per week. So, I respectfully suggest that Jet2's marketing strategy is NOT poor. The company cannot spend with reckless abandon; they deploy their limited resources to achieve the greatest possible 'clout' in the marketplace. And remember, the ultimate objective is to make a profit after expenses. Advertising is an expensive business.
