I fly a lot with work – 100 plus flights a yr for the last 3 yrs
Getting arsey gets you nowhere – smiling a lot, saying please and thank you does work for me. I don’t think I’ve ever had my hand baggage weighed and only rarely had problems at security etc – and I always fly economy but do have frequent flier privileges so can queue jump
The rules are fairly straightforward and if I’m paying £40 for a Ryan air flight I know to keep the bag weight to a minimum whereas with Klm I can take a camera bag, big courier bag and a suitcase on as hand luggage
I always try and avoid paris and heathrow for transit flights – unless both flights are T5 – personally I love travelling – and for every bit of hassle there are dozens of amazing experiences 🙂
