A traveler flying with Southwest Airlines reported being required to gate-check a backpack on a full flight, even though the bag appeared to meet standard carry-on size expectations and could likely fit under the seat.
The situation occurred on the final leg of the journey when the flight was full. The airline requested volunteers to check carry-on roller bags, and when not enough passengers complied, staff began requiring passengers in later boarding groups with roller bags to check their luggage. Despite having a backpack rather than a roller bag, the traveler was still instructed to check their bag at the gate.
The passenger expressed concern about the handling of the backpack, noting that it contained essential items, including medication, and that backpacks are not typically designed to withstand the conditions of checked baggage. They also observed that some larger roller bags remained in overhead bins, raising questions about consistency in enforcement.
The traveler is asking how common it is for backpacks to be gate-checked in such situations, what policies typically lead to these decisions, and how passengers might better avoid this scenario in the future when flying on full flights.
