Well ... this subject has been covered so many times and in so many threads in so many different forums of PPRuNe that, to point you to them will take a long time. For example:
http://www.pprune.org/passengers-slf...merged-ii.html [note that this is second such thread on FR alone!]
The key points (on ANY LCC) are that:
- They do not 'sneak in' ANY cost - unless they manage to hypnotise you. It is you - and you alone - who electronically agrees to what they are going to charge. Many threads in PPRuNe on this topic.
- If they decrease prices and expand capacity for part of the year and then reverse that - it's called 'capitalism'. If you can prove that two companies colluded to put another out of business, or that one company used predatory pricing - then do notify the trading standards officer in the area where the offence took place. Many threads in PPRuNe on this topic.
- If you have proof that a carrier is using 'technical failure' as a ruse for commercially non viable flight. - then do notify the trading standards officer in the area where the offence took place. Many threads in PPRuNe on this topic.
I don't mean to give offence to you but these questions are all
very old ground and I'm sure you can find threads to revitalise, rather than starting the whole shebang all over again.
