[MENTION=804859]plunet[/MENTION]. I understand your POV.
Yes, I skiplagged a flight a month ago. Everything went well. However, I had to wear 10 lbs of clothing, a laptop on my body when they were weighing the luggage! Yes, I was alone and did take a risk. I know the worst case, I will have to buy the last leg.

I think your advice is fundamentally not to use budget airlines, not to use different airlines for different legs, keep sufficient layover time - all is good, but it reduces risk and hence increases price. When I go google flight search, nowadays kiwi.com flight itin comes up. I guess they give you a risky / cheaper option - it is up to you to take it.
