Has this become the delay watch thread ?
I'm not sure of the obsession ? Unfortunately all airlines are subject to delays and cancellations, particularly in the (UK) summer months where aircraft utilisation is at its peak and with more passengers travelling it will always be harder to recover when a delay does occur. Airlines don't want these delays nor plan them on purpose. If anything, being on a TUI flight or other charter operator could probably be the best deal should you find yourself in the unfortunate event of a severe delay. They will endeavour to get you to and from your destination on a planned flight rather than just cancel and rebook whenever availabilty arises. They may also more often than not have the flexibility of using resort hotels to keep you in the event of an extreme/indefinite delay. They've also got a reputation on priding themselves with their ontime performance - which is available for all to see. So whilst a small number of flights may be going through a rough patch, in the grand scheme of things anc with a summer of horrendous slot restrictions ontop, they're probably not doing too badly.
