I recently (23 February) flew Dubai to Sydney (EK0412). Although we had some departure delays ex. Dubai, I had no issues with the standard of flight or flight crew. However in 31 years of international travel experience, this was the worst flight ever!. I was seated in economy 55G. Three toddlers who set up a rotational crying programme made it impossible to sleep. I was using my standard industrial strength earplugs - used annually at Formula One races - however these did not block any of their noise. Since I had a 'visual' with two of the toddlers and their parents I quickly realised that both children were teething. I am assuming that the other toddler located two rows behind just wanted to join in. Are there any recommendations for Noise Cancelling Headsets that would actually block this sort of noise? I have never needed any 'sleep assistance' when flying and actually have always managed several hours which have allowed me to arrive at Immigration in any country with some sense of reasonable attitude towards the relevant Immigration staff. This was very difficult this time - which I will raise in another discussion. Many thanks for any suggstions.
