Continental’s Travel Club offers OnePass members $5 back on every ticket you purchase at continental.com. In addition, Travel Club members receive special offers on travel and merchandise including hotel, cruise and vacation packages. The cost of the Travel Club was a very reasonable $10, but has recently gone up to $25 for an annual membership — still not a bad deal if you travel often with Continental — but another example of the airline industry grabbing at every dime to help with the cost of doing business.
