Tour (2)

Description

Can you find the flight number and the flight operator of the last flight that took her to the final destination?

E.g. GrabCON{AF226_Air_France}

required to solve The Tour (1) first.

Solution

From the previous task "The Tour (1)" , we see some interest clue : airline ticket and the car that came to the airport to receive her

Investigation :

1. What is Let's go! CAMPER which is on the car?
2. The barcode was leaked on that airline ticket picture so what that barcode is about?

So now we try to find Let's go! CAMPER and we get their website.

We can define her airline ticket now. The last location that she have a food is at Serbia and the car that came to the airport to receive her is in Antalya, Turkey . So it means that she fly from Serbia to Turkey. Here is an serbia ticket example:

Look at the example once, The ticket is very similar to her ticket. So We can detect that:

1. Her flight operator is : AirSERBIA
2. Flight No : JU XXXX

How we find Flight Number?

First we try find the type of barcode.

We see that it's a PDF417 barcode which according to IATA (wiki) standard. Easier way, we use online tool to read the barcode.

Look at the result, we can detect a pattern which look like Flight No. but what is BEGIST which stand before JU 0802? Base on IATA's code search:

• the 2-letter code of an airline or identify to which airline a 2-letter code corresponds
• the 3-letter code of an airport location or identify which airport uses a particular code

So BEGIST which means Origin to Destination. We can find the 3-letter code using this airport code list:

BEG = Belgrad (Beograd) - Belgrade Nikola Tesla International IST = Istanbul - Istanbul Atatürk Airport

Let's merge our info to get a flag base on example flag in description above:

1. JU 0802 = JU802
2. AirSerbia = Air_Serbia

flag = GrabCON{JU802_Air_Serbia}
