Which Indian airline introduced the Neticket scheme that allows a passenger to fly without ever visiting a reservation counter?

Introduction / Context:
This question tests awareness of early e ticketing initiatives in the Indian aviation sector. The Neticket scheme was one of the first efforts by a major Indian carrier to allow passengers to book and travel using internet based tickets without physically visiting a ticket or reservation counter, which marked an important shift toward digital transactions in air travel.

Given Data / Assumptions:
- The scheme is called Neticket. - It allows a passenger to fly without visiting a reservation counter. - The options are well known Indian airlines at the time. - We assume the question refers to the first airline that branded and launched Neticket.

Concept / Approach:
The concept here is business awareness related to aviation and service innovation. Many airlines eventually offered online booking and e ticketing, but Neticket was a specific branded initiative. The approach is to recall which public sector carrier emphasised online booking and introduced this particular scheme, especially in exam oriented general knowledge material that often highlights firsts and milestones.

Step-by-Step Solution:
Step 1: Note that Jet Airways and Air Sahara were private airlines which expanded aggressively, but standard exam references usually associate them with other branding campaigns, not specifically Neticket. Step 2: Indian Airlines, the government owned domestic carrier of that time, promoted internet based booking under the name Neticket and highlighted that passengers could travel with a printout and identification. Step 3: The question explicitly says the scheme allows a passenger to fly without ever visiting a reservation counter, which is exactly what internet based e ticketing does. Step 4: Match the scheme name Neticket with Indian Airlines, which is the pairing found in standard business awareness question banks. Step 5: Therefore, select Indian Airlines as the correct answer.

Verification / Alternative check:
You can cross check this information in older business and general knowledge compilations, where Neticket is consistently listed as an Indian Airlines initiative that promoted online booking in its early phase. Remembering that exam questions often reuse the same fact patterns helps you verify your choice during a test even if you do not follow aviation news closely.

Why Other Options Are Wrong:
Jet Airways did provide online booking, but its widely known brand campaigns were different, so Jet Airways is not linked to the specific Neticket scheme. Air Sahara also expanded its services but is not associated with the distinct name Neticket. None of these is incorrect because one of the listed airlines, Indian Airlines, did in fact introduce the scheme, so the generic option is not needed.

Common Pitfalls:
A frequent error is to assume that private airlines like Jet Airways were always more innovative and therefore must have launched the first internet based scheme. Another pitfall is to think every e ticketing service is basically the same and overlook that exam questions focus on the exact naming and branding used by companies. Focusing on the precise term Neticket and linking it to Indian Airlines avoids this confusion.

Final Answer:
The Neticket scheme was introduced by Indian Airlines.
