The Continental website is a key source of information about flying CO. Unfortunately, information can be a bit difficult to find at times.

Additionally, the FT forum on OnePass (CO's frequent flyer program) is a wonderful source about how things actually work. (For example, if one asks the OnePass Service Center about what happens when one is on the waitlist for a mileage upgrade and then becomes eligible for an Elite Upgrade Award (EUA), one will get a non-deterministic answer. The OnePass forum seems to have pretty well sorted out that you'd better have good evidence that you got an EUA or else you'll lose the miles.)

Continental has in recent years found out that there is a great market for non-stop services from the US (usually EWR) to underserved non-gateway cities in Europe; GLA, BRS and TXL are examples. These are flown with smaller aircraft (usually 757-200), offering a good BF (Business First class), and a substandard coach cabin.

Hub airports: Newark (EWR), Houston (IAH), & Cleveland (CLE). They also have a hub at Guam for their Micronesia division.
