According to a recent poll by Skyscanner, airline passengers have voted hidden charges imposed by carriers as the most annoying aspect of air travel. Hidden charges including fuel surcharges, charges for booking by credit card and checked baggage fees received 24 per cent of the vote. Hidden charges were closely followed by queuing, waiting for security clearance and waiting to board the flight, which polled 23 per cent. Other annoyances featured in the poll included: lack of seat space (15 per cent); fellow passengers (11 per cent); having to check in so early (eight per cent); poor staff attitudes and customer service (six per cent); waiting to take-off or disembark (four per cent); having to bus to and from the plane (four per cent); and waiting for luggage (by four per cent). Skyscanner's head of marketing, Rob Innes, said: 'It's incredibly annoying when you see a great flight deal, only to find the actual price is considerably higher once you've added all the extras. Mr Innes added: 'A transparent pricing system would win more favour with air travellers and avoid them feeling ripped off when they arrive at the checkout page. The good news is that if you study the small print and learn how to avoid the extras, you can still get great deals on flights'.
