A surgical airway is better than an arrested patient with a nice-looking neck. In real life emergency surgical airways are usually a bloody mess. The very obese patient presents special airway challenges. Pregnant patients, even when not in the least obese, often behave like obese patients from the perspective of airway management. If you never use the laryngeal mask airway in elective cases, you'll definitely not be elegant and slick when you try to use it in an emergency.
Fiberoptic intubation is usually ill-advised in dire emergency cases, even with experience.
This is especially true with an edematous, bloody airway.
