 Online Booking & e-Tickets

✈️ What Is Online Flight Booking?

Online flight booking allows you to purchase airline tickets through official airline websites or trusted booking platforms — without visiting a travel agency.

After completing your purchase, the airline sends a digital confirmation and an e-ticket, which has fully replaced the old paper tickets.

🛂 Security Screening & Passport Control – eGates, Biometrics & AI

Modern airports rely on automated scanners, biometric systems, and AI-driven analysis to improve safety and speed. Travelers now typically pass through two digital checkpoints: security screening and automated passport control (eGate).

🔍 1. Automated Security Screening

Next-generation scanners can detect electronics, liquid containers, and batteries without removing items from bags. AI analysis identifies potential threats using 3D imaging.

• Present your mobile boarding pass (QR code)
• Remove metal items and place them in the tray

🔁 Connecting Flights — Staying Informed & Keeping Your Luggage Safe

Connecting through busy airports can be stressful, especially with tight layovers. Modern apps and automated baggage-transfer systems make connections easier and more predictable.

📱 1. Real-time gate updates & notifications

Airline and airport apps send instant updates when:

• your gate changes
• your flight is delayed or departs earlier
• boarding begins
• your luggage is delayed in transfer

Always enable push notifications — they can save your connection.

🗺️ 2. Navigating transit zones

Large international airports offer digital tools with:

How to make a network cable - Crimping a network (LAN) cable.

 You don't have to be a computer network administrator to get into a situation where you have to attach a connector (RJ 45 or RJ 46) on the spot;

Simply, you bought a TV that also has LAN available, in order to be connected to the Internet wired, you need a network cable to your router. If the connection goes through the ceiling and you have to drill holes, it is difficult to run the cable with the connectors already installed.

The procedure itself is called "Crimping" and it is nothing complicated, the only thing that requires a suitable tool, and a suitable arrangement of wires considering the purpose of the cable.

So let's go;

You need a network cable of suitable length (every IT shop has it) and a pair of LAN connectors, and you can borrow a crimping tool:

First of all, the insulation should be removed from the mains cable, either with a tool or with a scalpel. What length of bare wires (pairs) should be left, you will understand on the spot when you try to push them into the connector, because fixing with pliers goes first over the insulation (physical contact) while at the same time establishing contact with the contacts (electrical contact), by breaking through their thin plastic sheath with sharp tin contacts (which are integrated into the connector).

How you will arrange your personal wires depends first of all on what type of cable you want to make: 

T568A or T568B

After that, the wires should be arranged according to the TIA/EIA 568 standard A or B. In case of making a crossover cable, one connector is made according to the A standard and the other according to B. For non-crossover cables, both connectors have the same arrangement and it does not matter whether A or B is used. For normal connection, a non-crossover cable is used.

The combination of these two standards (on one side one type of connection (T568A) and on the other another (T568B) is needed, for example, when you network two computers directly with a network cable...

That is, you connect their network cards directly, with a crossed network cable. (one standard to another)

When you have chosen the combinavia, insert your personal one into the connector, then into the pliers and, like any other good thing, just squeeze :)...

So step 1.

step 2.

Result: your cable is ready, connect it! In case it doesn't work, there are also testers to test the LAN cable....
