Numerous airlines offer flight conveyance services, but people prefer a particular airline over all others due to specific preferences. The most common concern of travelers when booking a flight is to find a pocket-friendly one to ensure their tour stays within their budget limit. From an affordability standpoint, the most commonly preferred airlines are Southwest, Spirit, Frontier, and Allegiant Airlines. You may wonder which one is the best among these airlines. Please refer to the comparisons below among these airlines and find the most suitable one.

1. Fare Affordability

All these four airlines are renowned for providing affordable flight fares. However, travelers are extremely inquisitive to know among these airlines which one offers the most pocket-friendly flights. According to the passenger reviews and flight fare price trends, Spirit Airlines offers the most budget-friendly flights. The second best in terms of affordability is Frontier Airlines, followed by Allegiant Air, and the last one is Southwest Airlines. Please note that other factors, such as travel season, flight destination, and route, influence ticket costs.

2. Seat Comfort

Besides affordability, comfort is the second thing that flyers generally look for when finding an ideal flight for their travel. All these airlines offer comfortable seats equipped with multiple features, such as on-seat screens, USB ports, adjustable headrests, a recliner, and much more. However, no other airline could defeat Frontier Airlines in terms of seat comfort due to their extra legroom space and the high-quality material used for the seats. 

3. Service Classes

Airlines understand that each passenger has a different travel budget and preferences for their flight travel, which is why they offer varied cabin classes to cater to their requirements and preferences accurately. Unfortunately, Spirit Airlines and Allegiant Air offer only one cabin class, limiting the flexibility of the passenger's choice. On the other hand, Southwest Airlines has outperformed other airlines because it provides four fare types: (i) Business Select, (ii) Anytime, (iii) Wanna Get Away+, and (iv) Wanna Get Away.

4. Flight Attendant Cooperation

No matter how affordable and comfortable the flight is, if the airline's flight attendants are not helpful and cooperative. Be it Southwest, Spirit, Frontier, or Allegiant Airlines, all these airlines offer excellent assistance to the flyers. However, according to the passengers' feedback and experiences, the most congenial and cooperative cabin crew is Spirit Airlines, whether for disabled passengers, senior travelers, infant flyers, or any other.

5. Guidelines and Regulations

Requesting changes, cancellations, upgrades, and special services becomes extremely tough if the airline has rigid and vague guidelines and regulations regarding different procedures, such as pet travel, flight cancellation, seat upgrades, etc. Out of the four airlines provided, Allegiant Air has the most flexible and explicit policies regarding multiple processes, such as baggage conveyance, special service requests, and much more.
