Spirit are not an easy airline to work with. You can try small claims court, as they have admitted liability by offering to pay for he passport. Make sure you have that in writing. You have to be realistic... put a fair value on the loss of one days holiday, plus the cost of he replacement passport... A bit for the inconvenience and file a claim for that. Make sure you have in wruting their admission that they were negligent and you can prove your actual costs as a result of their negligence. You should be aware that in most airlines terms and conditions are your agreement that they are not liable for your additional costs as a result oftheir failure to perform to contract. However, you may still prevail as they appear to have admitted negligence..it might be worth a punt.
