It would truly break my heart, if Spirit goes bust. Two bankruptcy filings, may not be bad,…read morerestructuring takes effort, skill and expertise. The airline service, its credit card, Savings Club, all of which I participate in, has come a long way. No complaints. Calling customer service is a nightmare. Yet, Spirit has been fine tuning all along. Now as I observe, their digital boarding pass, is one of the best in the business. All this serious improvement, can only materialize with a competent management team. This incudes the vital check in personnel and gate staff, all important components, for an enjoyable flight. I have always observed consistent and high class service, when flying from BUR to LAS, on my favorite flight path. In this context, I am talking about Supervisor Sukhmani and her colleague, Melissa. Almost always, encounter them before embarking. Both provide high class customer service. A caliber of fine friendly touches, I don't experience on any major US carrier like for example (cough, cough), American. Yes' it's true. Spirit, though still growing, embodies customer care, everytime, consistency, always smiling, and providing top notch customer service.
