Given a travel related situation, and given a specific question about the situation, summarize the question into a title

I think it's better if I tell a short example:

I plan on going from country A to country B, and I find out that it is cheaper if I pass by country X.
However, the flights from A to X and then from X to B have to be booked separately with unrelated airlines 1 and 2.

Is it usually possible to ask airline 1 to automatically transfer my luggage on arrival to city X, to the plane managed by airline 2?

Or do I have to grab my luggage myself and go through customs and airport-security?

Luggage transfer between unrelated airlines

In the last four days I've driven my motorbike from Milano to Kalamata going through a few nations on the east side of Adriatic sea, and in a couple of occasions I found myself crossing two customs to enter or exit a country (in both cases it was night, and cold, and I was freezing, and after driving for hours and hours, so I did not take note of which border...but probably entering Montenegro and exiting Albania)

Why is that? I noticed that in all occasions one custom asked for both my passport and my bike documents and the other custom asked for just my passport, but still it doesn't make much sense.

Why two customs/immigration controls?

I plan on going to Egypt around Christmas and I have always hated the thought of being a tourist. I want to blend in and experience what it is like to be there without being regarded as a tourist all the time.

I have never been to Egypt before and I wonder if it would help me to wear native clothing to sort of disguise my self and further what would be the preferable clothing?

I am male, 32 years old, caucasian and close to 2 meters tall - I tend to stand out in a crowd :)


What to wear in Egypt to blend in?
