People are generally very excited about their trip and, therefore, in excitement, they would want to carry everything with them. But, this is the mistake done by most of the passengers. You can carry a limited amount of bags with you. So, there is no point in making extra bags for the journey. You can be charged extra for each extra bag that you will be carrying that can result in spoiling your mood. Therefore, you should go through the baggage policy of the airline on which you are traveling.
This was the Sun Country airlines baggage policy. If the passengers have some concerns related to this policy, then they can definitely contact customer support executives for discussing the query.
Ideal flights there and back. One disadvantage - you have to pay for portable overhead baggage, and you just get a complimentary pop, tea, espresso, or water on the flight - where with another respectable aircraft - no portable charges and complimentary refreshment and bite is incorporated..
