I suppose then that the above statement is true.
Be careful with blanket statements. It is true with
certain operators and not with others. Just like networking. You (or I) can't say that networking will always work, it won't. So I wouldn't recommend giving up sending CVs and phoning airlines, rather increase your potential to get called for a selection by adding networking (the bit most people aren't doing effectively) to your armoury.
I know it can appear a thankless task getting PFO letters, 'no thanks' on the phone or even worse 'don't ever contact this airline again!' but all your effort will get no reward until that one phone call asking if you are available for interview...............
So keep up the effort and make sure you are 'managing' the task as efficiently as you can and not leaving any stones unturned. It will happen and the market is definitely improving.
