The entire ACMI and non-scheduled sector is, by and large, a fisherman's job. The sales team may or may not get a sound contract for a long-term flight programme, especially in times like those. One-off flights are also not a given - you may get 10 of those this month and then none for the next 2 months. So, by default, go in with your eyes wide open. You may be crazy busy at times and then idling for months on end. And the latter hurts a lot if you don't have a proper base salary to see you through times when there's little to no flight activity.
What (kind of) gives some hope is that Smartlynx seem to have sound connections with travel agencies in their region. So, some charter work will be there for as long as international travel to any leisure destination remains a possibility. However, what will happen with all the aircraft which normally worked for clients abroad? My guess is that few of them will be flying a meaningful schedule this summer. May I be wrong. And this is what will determine how many pilots will be needed.
