1. Touts trying to rip me off
Wherever I go whether local or international travel, I always end up being approached by touts trying to rip me off. The worst experience I had was in Poipet (Thailand-Cambodia border) where I was approached by a person and I was being told that the free bus is no longer operational and that he can offer me a shared taxi going to the terminal. I was quite certain that it wasn’t true and sure enough after just about 5 minutes the bus arrived.2. Delayed flights
This is always annoying and most of the time it happens almost every flight I have.
How to avoid this? There is no way you can avoid this but you can get rid of the boredom by bringing a book, netbook, laptop or tablet to kill the time. If you are not keen in bringing gadgets when flying to your next destination, a simple pen and paper will do and start writing. You an also start talking to a stranger, I’m pretty sure you will learn some new things from him/her
3. Long queue at the check in counter
We do not know for sure how many people are booked on a certain flight so sometimes we end up queuing for a really long line upon check in. This is quite annoying especially when there are no available comfortable seats in the pre-departure area.
How to avoid this? Check in online when it’s possible or come in a little late. Airline reps will prioritize you when you’re flight is about to close the check in counter. Just make sure you do not miss it, otherwise it’ll be a pain in the ass!
4. Arriving at the terminal and realized that the bus/train just left
This is really annoying especially when you arrive in the morning and just minutes away and the next trip is either in the afternoon or worse the next day.
How to avoid this? Make sure you come in early and do extensive research a day before your trip. Make sure the reference that you are looking/reading is updated otherwise you might just arrive at a wrong time or worse a wrong place (location of the terminal is transferred). Also make sure you ask around, there maybe alternative routes to reach your destination. If no alternative routes and the next trip is more than 3 hours away, you may want to explore the place or just sit back and relax.

I agree with number 1, dishonest drivers suck and drives tourists away from a place.
Right christian! Anyway, thanks for dropping by
Number 3 and Number 4 happened to me in my recent trip to South Korea – missed the KTX train and almost missed a flight to Seoul. All of them good learnings though 🙂
Right Mariane, we learn from our good and not so good experiences 🙂
