I am really fed up with United and Continental airlines. Their websites don't tell me what is the baggage allowance for carry on. They only tell the charges for 1st & second bag, and don't mention the carry on allowance at all. I found out about it because I called the airlines (Continental/Austrian/Lufthansa) last week and I got lucky because after holding for long periods, I got to talk to a person that gave me some information. The problem is there is a huge discrepancy among airlines when it comes to baggage allowance. BTW I am flying economy. I am flying Continental (but operated by United) within the USA and on to Euorpe, connecting with Lufthansa in Frankfurt to go to Asia. Lufthansa allows just 18 lbs for the carry on. I am supposed to follow the baggage limits for Continental, which is 40 lbs, but the allowances are so different that I am worried that I may be told something else at the airport. I no longer trust the airlines when their website says to follow the baggage allowance for the first airline you board. I don't want to end up paying just because I exceeded 18 lbs (which is an outrageously low allowance, IMO). On the way back, Austrian airlines also allows only 18 lbs. Last week when I got lucky and got a person to talk to when I called Continental. I was told 40 lbs for the carry on (for the first suitcase they were pretty consistent- no charge for 1st bag if it's less than 50 lbs; $70-$83 for the second bag, so I will not be carrying a second bag). The Continental flight will be operated by United, so I called United to find out the baggage allowance because of the discrepancy between Continental & the European airlines. I can't get the right person when I called United's 800 number. They kept giving me a run around, transferring from one person to another, but not giving me an answer. I finally gave up and hung up. So far I have found United to be the worst airline in customer service, but may be there are others that are even worse. Why is it so difficult to get the information? I am VERY frustrated. I would really like to have that 40 lbs limit for the carry on, on my way. On the way back I can arrange to put all the heavy things in the checked bag. As it is, I don't like heavy carry ons, but I am used to checking two bags free of charge, and here are airlines that want to milk every dollar out of me. Why must travel be so painful? Please let me know if you have experience connecting on one of the US carriers with a European airline to go to Asia. What was the baggage allowance? Is it the same (40 lbs) on Continental and United? I already know the European airlines allow only 18 lbs. At least here on fsu I am sure to get an answer, and you don't even get paid for it.
