Cons: The BoA personnel in La Paz at surcusal at the airports in LP and Santa Cruz were very pleasant and accomodating. There was an awful women at the check in counter in Madrid who insisted that I should change my seat assignment makng up a variety of reasons but I held fast to my assignment. Then, perhaps oit of spite she tried to force me to check my carry on bag rather than carry on board. Luckily a kind man from baggage personnel told me there was no problem with my bag and just to proceed on to the gate. All my baggage was considerably below weight allowances permitted.
