The flight from Boston to Miami went flawless . Nobody sat next to me so I was even able to put up all of the arms and use the three seats around me as a small bed . Sadly , Miami to San Jose was another story .

Question: What may be the reason they could n't use the seats as a bed on the second flight ?
Answer: There were more people on the plane .They were n't tired on that flight .The flight crew did n't allow that .There was too much turbulence .
