eAbbasi, those are minimum connection times if your journey is all on one ticket. That's not the case here.

eAbassi's information, as Jeff_Costa_Rica suggests, is dangerously wrong. WOW requires you to check in 45 minutes before flight time (suggested time is 2 hours), and you must check in only at the airport - no online check-in is available.

It's really a question of how much risk one is willing to accept. 2:40 between scheduled flights will be sufficient maybe 90% of the time. Rest of the time, the flight from Charlotte might be badly delayed or canceled. Maybe the OP is willing to take that risk, maybe not. Each of us has different tolerance for risk compared to hanging around an airport for multiple hours.

As a practical matter, it takes about 15-25 minutes from the time OP's plane arrives at Boston to go from his/her plane (AA/US terminal) to the WOW check-in counter. (Security is almost irrelevant, because security comes after the 45-mis-before-flight check-in, and I have never waited even close to 45 mins at BOS Int'l terminal security.)

ok, they might be unrealistic but these are minimum connection times as they have 2 hours and 40mins and I think they can make it, may be i am wrong but let the guys take chance at least or if suggest them if there's any alternative.

They can make it . . . . IF they arrive on time which they have no control over. See, the thing is, people who book these sorts of flights are often ones who cannot afford to lose their booking if things go pear shaped. They do save a little bit but if they miss the flight they lose all rights. So it is a crap shoot.

A couple hundred $$ savings can be a false economy
