Budget airlines can be a cost-effective choice for travelers, mainly when focusing on short-haul flights or routes where the trade-off between cost and amenities is acceptable. However, it's crucial to conduct a comprehensive cost analysis. While the base ticket prices may be lower, budget airlines often charge extra for services that traditional carriers include in their fares. Travelers should factor in fees for baggage, seat selection, and other amenities to determine the overall value and convenience of choosing a budget airline for their journey.
